Signs of pregnancy
A woman usually guesses she is pregnant when she notices some of these signs:
- No menstrual bleeding
- Nausea
- Feeling tired
- Urinating more often
- Tender, growing breasts
- Weight gain
A blood or urine pregnancy test can tell for sure starting about 2 weeks after the woman becomes pregnant (a month after the start of the last menstruation).
By about 4 ½ months of pregnancy, the mother can feel the baby move and a health worker can hear the baby’s heartbeat with a fetoscope.
When will the baby be born?
Pregnancies last about 9 months (10 moon cycles, or 40 weeks). To figure out when the baby is likely to be born:
Add 9 months plus 7 days to the first day of the last normal menstrual bleeding. That is the due date. Most babies are born between 3 weeks before to 2 weeks after this date.
For example, suppose the woman’s last period started February 10.
February 10th + 9 months = November 10th
November 10th + 7 days = November 17th
The baby’s due date is November 17th.
