Fetal Development: Week 2

Gestational Age: Week 2

Officially, you are still not pregnant yet but something magical is about to happen.

What Happens in Week 2 of pregnancy?If you have a regular 28 day cycle, ovulation can occur between days 10 and 18 from the start of your last menstrual period.

The four main phases of the menstrual cycle are:

  • Menstruation
  • The follicular phase (ovaries produces between 5 to 20 follicles containing immature eggs)
  • Ovulation (an ovary releases a mature egg)
  • The luteal phase (increase in progesterone plus estrogen maintains the thickened lining of the uterus ready for implantation).

Your fertile window is during the last 5 days of the follicular phase (when an egg follicle on an ovary gets ready to release an egg) plus ovulation day. 

Therefore, if you have unprotected sexual intercourse during this period, conception and fertilization of your egg by the sperm can occur between the end of week 2 and the middle of week 3 of your menstrual cycle.

Tip for week 2

Even though you may be just pregnant, you will still not feel any body changes just yet.

If you are dying to know if you are pregnant, hang in there for a little longer as the fertilized egg starts to produce the hormone human chorionic gonadotropin (hCG) about 4 days after fertilization and it takes some time to be detected in the urine (home pregnancy test).
