1st Month Week 1 | You’re not pregnant. This is the week of the start of your last period. as the uterus sheds its lining and causes bleeding, the hormones are preparing another egg for release. |
Week 2 | You’re still not pregnant. The uterine lining is thickening and ovulation (the release of an egg) is getting ready to occur. You may feel a twinge pain as ovulation occurs. |
Week 3 | This could be the week. When an egg is released into your fallopian tube, it meets up with your partner's sperm. (There are 350 million sperms in the average ejaculation that have a chance at making the trip into the fallopian tube. The ones that make it will wait there for an egg as long as four days) when the sperm penetrates an egg, fertilization (conception) occurs. The fertilized egg is called a zygote. Immediately the egg begins dividing into identical cells as it floats down the fallopian tube to the uterus. Now you're pregnant. |
Week 4 | There’s lots of action going on that you are completely unaware of. your little zygote finds its nesting place in the uterus and is now called blast cyst. Once in the uterus, it divides in half: one-half sticks to the uterine wall and becomes the placenta (the life-support system that brings nourishment into your baby and takes waste out). The other half will become the baby. Transvaginal ultrasound shows a gestational sac (a small circle that will become the baby's home). by the end of this week, you will have missed your period, giving you the first sign that something's up. Some women see a slight spotting called implantation bleeding that happens when the blast cyst nestles into the uterine wall. |
Week 5 | At this point a pregnancy test can confirm the pregnancy. Your baby is about the size of an apple seed and is now called an embryo with a beating heart of its own. The placenta and the umbilical cord are in full operation. You would be shocked to see how rapidly your baby is developing: =) the head and tail folds are distinct =) the primary brain vesicles form =) the nervous system begins to develop =) two heart tubes are fused in the midline and begin to contract |
Week 6 | Your little embryo is dropping its calling card. This is the week the physical sensations of pregnancy usually appear: nausea, sore breasts, fatigue and frequent urination are all signs of this incredible growth process. The embryo looks more like a tadpole than a human, but the body is growing rapidly: =) the head, tail and arm buds are easily recognizable =) the optic vesicles and lens form =) limb buds are present =) the earliest form of the liver, pancreas, lungs, thyroid gland and heart appear =) blood circulation is well established. =) the heart bulges from the body =) the cerebral brain hemispheres are enlarging in the stomach area, the primary intestinal loop is present |

Weeks 36 to 37 | =) more fat layers are added to help control body temperature after birth |
Week 38 | =) the baby is now "full term" this means that if he's born today, he'll be considered a full grown baby. Babies born before 38 weeks are called premature babies |
Week 39 | =) the baby sheds her fuzzy layer of lanugo hair and the vernix caseosa, which is the skin coating that covers a fetus to protect the skin. The baby swallows this waste and will discharge it as his first bowel movement in a blackish mixture called me conium =) all organs are ready to function outside your womb =) the lungs are the last organs to mature. They should be fully developed by this time |
Week 40 | =) bingo! This is the due-date week when your baby just might make her entrance. But then again maybe she did that last week or will wait until next week. Remember that due dates are rarely exact. (only 5% of babies are born on schedule) even carrying a baby to week 42 is considered normal. After that, the baby is post-term. |
