Pregnancy Calendar


Pregnancy is the carrying of one or more offspring, known as a fetus/embryo, inside the womb of a female. In many references, pregnancy is typically broken into three periods, or trimesters, each of about three months, where these distinctions are useful in describing the changes that take place over time.

Pregnancy Phases

First Trimester (W1 – W13)

In first trimester, your pregnancy begins as your body gears up for ovulation and prepares for fertilization. As the first trimester comes to a close, your baby’s is grown up and will have size of peach, though you may not be feeling too peachy about your sex life right now.

Second Trimester (W14 – W27)

In this second trimester, it’s all about hair now as your baby sprouts some on his head, eyebrows, and body. As for Mom, those first-trimester pregnancy symptoms should be easing up a bit. As the second trimester come close, your baby moves on to a whole new growth chart this week, while your swollen feet and ankles may need a growth chart of their own.

Third Trimester (W28 – W42)

In Week 28, your baby should start blinking their eyes and dreaming while you may be dreaming that the pain in your derriere will disappear. And started from week 37 your doctor may check for labor signs, while your baby prepares for birth by sucking, turning, and breathing in the womb. Week 37 – 42 are the period of labor where W40 is the official end of your pregnancy. You should be sensitive for labor signs and consult your doctors immediately if you feel something unusual or different than normal labor symptoms.

The expected date of delivery is 40 weeks counting from the first day of the last menstrual period, and birth usually occurs between 37 and 42 weeks.Though pregnancy begins at implantation, it is more convenient to date from the first day of a woman’s last menstrual period, or from the date of conception if known. Starting from one of these dates, the expected date of delivery can be calculated using the Naegele’s rule for estimating date of delivery. There are more sophisticated algorithm takes into account other variables, and usually can be detected when they go to the doctor.

A woman is considered to be in labour when she begins experiencing regular uterine contractions. While childbirth is widely experienced as painful, some women do report painless labours, while others find that concentrating on the birth helps to quicken labour and lessen the sensations. Most births are successful vaginal births, but sometimes complications arise and a woman may undergo a cesarean section.
