3 Weeks Pregnant

| September 28, 2011 | 0 Comments

If you’ve followed our advice and coupled on or around the 14th day of your wife’s menstrual period, it’s now time for fertilization to occur. Things are beginning to get interesting now!

How’s the baby coming on?

The egg meets the sperm

Mommy’s egg has now reached the fallopian tube (oviduct) and so has the sperm. The sperm will now penetrate the inner part of the egg to fertilize it, which will subsequently begin moving towards the uterus. The journey to the uterus can take around 7 to 10 days, and throughout this time the egg, now to be referred to as the blastocyst, undergoes cell division. By the time it reaches the uterus, it is approximately 0.1 to 0.2 millimeters in diameter.

Only one sperm does the work – usually

Many sperms can penetrate the outer layer of the egg, but only one successfully enters the inner part where fertilization takes place. The baby’s chromosome is formed, by fusing the chromosomes coming from the two parents. The gender of your baby is decided by the nature of the sex chromosome that the fertilizing sperm is carrying.

Fertilization by two different sperms

There are cases where two eggs are released, as stated earlier. In such rare cases, these two eggs are fertilized by two different sperms in the oviduct. This causes the mother to give birth to dizygotic or non-identical twins. If on the other hand, the one fertilized egg later gets divided into two, identical twins are born.

Changes inside the Mommy

You’ve got less than 9 months before you have a baby in your arms! The process has begun. During this “initiation week”, you may experience bleeding or spotting upon implantation of the blastocyst in the uterine lining. This is to be considered quite normal. But it’s always useful to visit your doctor for a checkup to eliminate any risks of complications.

Immunosuppressant protein

As response to the implantation, your body will begin releasing an immunosuppressant protein which is termed EPF, or Early Pregnancy Factor. This prevents your body’s immune system or “security guard” from treating your baby as a foreign object, in order to protect it.

Daddy needs to?

Daddies, at this stage, should keep trying for conception throughout this week. This gives you an opportunity to enjoy the moments spent with your partner, when you are at the verge of beginning a new life. Also keep in mind that depending on your own usual routine, your sex life may drastically change once your partner gets pregnant.
