Pregnancy is a 40-week period, starting on the first day of your last menstrual cycle. If ovulation and fertilization take place at the right time, then you should be able to conceive by the end of the second week or the beginning of the third week (1). However, it all depends on the length of your menstrual cycle.

So, how would you know if you have conceived during the second week? MomJunction explains the pregnancy at two weeks, the signs to look out for, and the baby’s development.

What Is Happening In The second Week of Pregnancy?

If the sperm meets the egg successfully, fertilization takes place in the second week. You may experience physical discomfort due to hormonal fluctuations in the body. But you may not yet realize that you are pregnant. You will still have to wait two more weeks before you can confirm the pregnancy.

2nd Week Pregnancy: The First Step Towards Conception

The first week of the menstrual cycle is associated with the shedding of the uterine lining. If you have a regular 28-day cycle, you can ovulate by the end of the second week.

How to know you are ovulating?

A woman with a 28-day cycle generally ovulates on the 14th day. Depending upon the length of the cycle (shorter or longer), the ovulation may vary between the seventh and the 21st day (2). Here are some signs of ovulation (3):

  • Consistency of vaginal discharge: Cervical fluid resembling egg whites and greater than usual fluid discharge, are indications of ovulation. But these are not sure shot signs because every woman has discharge typical to her and different than other women.
  • Basal body temperature: Tracking the basal body temperature can help you determine the day of ovulation. As you near the day of ovulation, there is an increase in the temperature and on the day of ovulation it could be half a degree higher.
  • Change in the cervix: During ovulation, the cervix is soft, high open and wet. But woman may take time to feel the changes between normal and ovulation cervix.
  • Light spotting or brown discharge: It happens when the maturing follicle grows, ruptures, and causes bleeding.
  • Tenderness and soreness of nipples: A fluctuation in the level of hormones just before and after ovulation cause this soreness.
  • Mittelschmerz: It is the term for the pain in the middle or one side of the lower abdomen and the pelvis during ovulation. The mild, twinging effect lasts for a few minutes to hours (4).
  • Ovulation test kit: This kit helps determine your ovulation time by tracking the level of luteinizing hormones in the urine sample. If the test is done correctly, the results are about 99% correct.

So, if you have ovulated in this week, and had unprotected sex three days before ovulation and on the day of ovulation, you are likely to conceive.

How Is Your Baby Developing During The Second Week?

The second week marks the fertilization of the egg that later develops into an embryo and a fetus.

During ovulation, one of the mature follicles will rupture and release the egg into the fallopian tube. If intercourse happens during this time, the sperm ejaculated into the vagina will swim upward into the fallopian tube. Out of the million sperms traveling into the uterus, only one gets the chance to fertilize the egg.

Each sperm has a sticky end that attaches to the protective shell of the egg and then penetrates into it and fertilizes it. Fertilization occurs within 12 to 24 hours after ovulation (2).

Capacitation of the sperm

Sperm can live inside the fallopian tube for three to six days (5). So, if intercourse happens two or three days before ovulation, the sperm gets enough time to mature inside the fallopian tube.

This process, wherein the sperm undergoes various physiological changes (6) to penetrate and fertilize the egg as soon as it is released, is termed as capacitation.

Over the next few days, as the fertilized egg travels down into the uterus through the fallopian tube, it undergoes cell divisions to form a blastocyst that finally implants on the uterine wall.

If the fertilization doesn’t take place, then the egg is ejected through the vagina during the next menstrual cycle. If you do conceive, you might experience common pregnancy symptoms, although they differ from woman to woman. Read on to know more about the symptoms of 2nd-week pregnancy.

Can A Pregnancy Test Confirm The Pregnancy At Two Weeks?

Soon after the conception, the level of hCG hormone may not be at a detectable level. So the possibility of getting a positive result on a pregnancy test is relatively low. However, highly sensitive pregnancy test kits claim to detect it.

Since you are not sure whether you have conceived during the second week or not, you may want to continue with your efforts to get pregnant.
