Pregnancy Week 1 Symptoms, Early Signs, FAQs, Precautions 2022


Pregnancy Week 1 Symptoms, Early Signs, FAQs, Precautions will be discussed here. Good luck on your journey to parenthood. In most cases, your due date is determined by the first day of your last menstrual period (LMP). Therefore, the countdown to your 40-week pregnancy has already begun, about two weeks before conception.

Pregnancy Week 1

Despite not being pregnant yet, the first week is an important time for preparation. While your body is undergoing a new cycle to achieve pregnancy, you and your partner should discuss your feelings and expectations openly, make healthy lifestyle choices, and make sure you choose the right doctor.

When you spot the telltale pink lines on a pregnancy test, you are probably further along than you thought. In this article, pregnancy week 1 refers to the literal first week of pregnancy, beginning one week after conception. Menstrual irregularities are often the primary symptom of pregnancy in its early stages.

Pregnancy on its Start

Even though most women don’t know when they ovulated – and few do – pregnancy is calculated this way since it’s so difficult to be sure of when your baby was conceived. Around the time of your ovulation, you are likely to have a few intercourses, especially if you are trying to get pregnant. So you will probably be about four weeks pregnant by the time you miss your period and find out you are pregnant!

You may not even know you are pregnant when you begin your journey to pregnancy. The first three weeks of your pregnancy may be completely free of symptoms. Your womb will be occupied with many different things. Find out about the transformation, signs, and symptoms of pregnancy in the first month, calculating your due date and your progress toward delivery by reading on.  

Pregnancy Week 1

1st week of pregnancy with your baby

During the first week of pregnancy, you won’t see your baby yet. An egg inside your ovaries will begin to develop and mature in the first days of pregnancy, ready to be released if it’s fertilized. It’s during your period when about 20 eggs can still be found inside the ovarian follicles, and this is when they begin preparing for your next period. More than one egg will rarely be released into the fallopian tubes during a cycle.

While there’s no baby yet to measure, your body is preparing to conceive. During the first week of pregnancy, a woman’s egg becomes mature, making it the giant single cell in her body.

During your first few days of pregnancy, your body will begin to go through the cycle known as the ovarian cycle. It usually starts at the same time as your period. The hormone called follicle-stimulating hormone (FSH) stimulates immature follicles to prepare for ovulation at first. 

One egg becomes dominant between days 5 and 7 of your cycle. It is usually the egg with the most potent blood supply and produces more estrogen. Your uterine lining will also thicken due to estrogen.

A dominant egg matures and waits for ovulation during the follicular phase.

Pregnancy Week 1 Symptoms

Women who are not experiencing pregnancy symptoms may only experience a few mild symptoms of fatigue, tender breasts, and mild cramps at week 1 of Pregnancy.

According to medical professionals, a woman’s last period is typically the first day of pregnancy week one. She was considering week one since the last menstrual period allows a woman to calculate the estimated pregnancy due date, even if she is not pregnant.

First week of pregnancy symptoms 

Every woman and every pregnancy experiences different pregnancy symptoms in week 1. As per the Office on Women’s Health, a missed menstrual period is the most common sign of pregnancy.

These are other symptoms of early pregnancy:

  • Vomiting with or without nausea
  • A change in breast size, tenderness, swelling, or tingling may occur
  • Urination frequently
  • Anxiety
  • Temperature raised at rest
  • You feel bloated or gassy
  • Mild cramping or discomfort in the pelvis without bleeding
  • Feeling tired or fatigued
  • Mood swings or irritability
  • Aversions to or cravings for food
  • Increased olfactory perception
  • Taste of metallic metal

Symptoms of pregnancy are not all the same for everyone. Also, it should be noted that noticeable symptoms do not always accompany early pregnancy.

If someone wants to know if they are pregnant, they should take a pregnancy test.

Early signs of your Week 1 pregnancy 

Ovulation produces an egg, which sperm fertilizes, and conception or fertilization occurs. March of Dimes reports that this usually happens after the beginning of the menstrual cycle.

Planned Parenthood says that implantation starts about 6–7 days after conception. Fertilized eggs attach to uterine linings during this phase. As the egg moves in the uterus, blood vessels may be ruptured, leading to cramps and light bleeding.

Pregnancy Week 1 Bleeding

Pregnancy can be detected early with implantation bleeding. Implantation bleeding is not like menstruation. A small amount of pink discharge or a single spot of bleeding describes light bleeding instead. There may be spotting that lasts for several hours, or it may last for several days.

Pregnancy Week 1 Cramping

It is also common for women to feel mild cramps when an embryo attaches to the uterus wall. Typically, women may experience cramps in their abdomens, pelvises, or low backs.

An uncomfortable cramp may feel like a stinging, pulling, or tingling sensation. Women may experience minor cramping, while others may experience occasional discomfort that comes and goes.

Fetal development during week 1 of pregnancy

During pregnancy’s first week, there has not been any fetal development since conception has not yet taken place. Despite this, you can begin taking steps to achieve a healthy pregnancy. 

Pregnancy is already in the works between your egg and the father’s sperm. It is vitally important to have healthy cells during pregnancy, which must contain 23 chromosomes each. Genetic information about you and your partner is stored on these 23 chromosomes. Having 46 chromosomes makes you a baby!

In the long run, taking prenatal vitamins and maintaining a healthy lifestyle can help you conceive a healthy child even if there is no baby yet.

Week 1 of pregnancy: your body

Your last menstruation occurs during the first week of pregnancy. According to your estimated gestational age, the first day of your pregnancy will be when you start menstruating.

During these days, your body is removing the eggs and uterine lining from last month. Pregnant women, and women starting their periods, often experience heavier menstrual flow during the first two days. You will feel more prepared for the new cycle this way.

Your uterine lining or endometrium will begin to thicken again once your period ends, and a new egg will have already matured. After conception, the fertilized egg implants itself in this lining, ready to begin growing.

Pregnancy Week 1 belly

Your first week of pregnancy, or the following few weeks, won’t show you a baby bump. Due to hormone changes associated with menstruation, you might feel a bit bloated due to fluid retention this week. Women may also experience cramps and abdominal tenderness during their period. 

Menstruation symptoms vary from woman to woman, and what you’re experiencing should be similar to previous periods.

Pregnant ultrasound week 1: is it necessary?

In the first week of pregnancy, an ultrasound isn’t essential. You might need one if you haven’t been checked out before conception or if you’ve had trouble conceiving. At this point, an ultrasound may be able to diagnose fibroids or polycystic ovarian syndrome as anatomical abnormalities making conceiving difficult.

Pregnant lifestyle during week 1

You can improve your chances of getting pregnant by making lifestyle changes if you’re trying to conceive. A few examples include:

  • Eating healthier foods will help you get pregnant faster despite the lack of a specific fertility diet. Ensure your diet contains leafy greens, mercury-free fish, seeds and nuts, complex carbohydrates, fruits, and plenty of water.
  • Stay away from alcohol, tobacco, excessive caffeine, simple carbs, trans fats, and environmental pollutants even if you are not pregnant.
  • You should start exercising as soon as you decide you want a baby. Getting in shape before pregnancy is an excellent way to stay in shape!
  • Studies have shown that women who do not get enough sleep often have difficulty getting pregnant.
  • Track your cycle using a menstrual calendar such as Flo to determine how long your cycle lasts, when your ovulation will occur, and when it will begin.

Pregnant women’s sexual behavior at week one

While you will not be on your fertile window during your period, you will still be about 14 days away from ovulation during your first week of pregnancy. Still, you should begin practicing now!

Even sex a few days before ovulation can result in pregnancy, as Sperm lives five days in the uterine cavity. When you decide that you are ready to conceive, try not to use a lubricant. Lubricants can cause sperm to swim more slowly and change their pH balance inside the vagina. 

Pregnant checklist for week 1

Here are a few ways you can prepare your body for pregnancy even before conception:

  • Before pregnancy, take prenatal vitamins
  • Menstruation cycle tracking
  • Consult your doctor before you become pregnant
  • Smoking should be stopped
  • It would be best if you reduced your caffeine consumption
  • Make exercising a priority
  • Make sure you get enough sleep
  • Healthy eating
  • Gather your family histories and those of your partner

What should you ask your doctor?

You need a pre-conceptional checkup if you’ve decided you’re ready for a baby. Prenatal vitamins before pregnancy, what lifestyle changes you should make, and how to calculate your due date can be discussed with your doctor. These dates can be determined by tracking your cycle.

Pregnancy week one is commonly divided into 3 phases that take a little longer than 13 weeks each. A full-term baby is born when the gestational age is 39 to 40 weeks.   To avoid neonatal complications, it is recommended to deliver twins no later than 38 weeks gestation. Your doctor can determine these dates even before the first ultrasound by tracking your cycle.

Your body has already begun preparing itself for pregnancy even though you don’t see a baby during the first week of pregnancy. Therefore, improving your chances of having a healthy pregnancy is already possible. 


Pregnancy symptoms are different for every woman. Some women may notice symptoms, such as spotting or a headache, during pregnancy week 1. Others may only experience a missed period. Some women will have no symptoms at all.

Whether a person has symptoms or not, the best way to determine if they are in pregnancy week 1 is to take a pregnancy test.
