1 Week to 2 Weeks Pregnant

During you are 1 week pregnant and 2 weeks pregnant, you may not even be certain that you are pregnant yet! Many women experience few if any symptoms at all. Weeks one and two are mostly consumed with the process of ovulation and fertilization. During pregnancy week 1 and 2 your body will produce estrogen and progesterone in varying amounts to prepare the body for ovulation, when the ovaries release an egg. While this is technically considered the first week of your pregnancy, baby is still only a glimmer in your eye (and an egg in your ovary). The first day of your period is considered Day 1 of the 280 days of your pregnancy even though conception won’t occur for another 14 days.

During weeks one and two an incredible number of changes are occurring in your body. Your hormone levels have changed significantly to ensure the uterus creates a rich lining of tissue, which will support your fertilized egg after conception.

During weeks one and two, your ovaries produced ripe eggs in vessels called follicles. During ovulation, which typically occurs around the 14th day of a menstrual cycle that is 28 days long, one or more of your eggs will burst out of your follicles. Your eggs will then wait patiently in the Fallopian tubes where sperm can fertilize them. Did you know it takes roughly about ten hours for sperm to reach the egg?

When your partner’s sperm and your egg meet, life begins! In the early weeks, your baby’s gender is determined. Sperm carrying a Y chromosome generally results in a baby boy, while sperm carrying an X chromosome generally results in a bouncing baby girl.

During weeks one and two, your fertilized egg, otherwise known as a zygote, will divide into multiple cells and starts burrowing into the rich lining of your uterus.

At this point, your precious baby is simply a ball of cells that transforms into a blastocyst. The blastocyst consists of an inner cell mass that will eventually transform into the embryo; another cavity that becomes the amniotic sac, and an outer cell body that will become the placenta. It is absolutely amazing how your baby develops from this seemingly primitive ball of cells!

Remember to avoid alcohol, smoking and drugs as they can lead to birth defects as well as respiratory problems, low birth rate, fetal alcohol syndrome and other health problems!
