Pregnancy, also known as gravidity and gestation, is the time during an offspring forms and develops inside a woman. Multiple pregnancy occurs when more than one offspring is involved, such as with twins. Pregnancy can occur by sexual intercourse or with the aid of modern assisted reproductive technology. Pregnancy lasts a span of 40 weeks from the last menstrual period and ends in childbirth (9 lunar months), each month measured about 29 and a half days, about 38 weeks after fertilization.

Pregnancy is typically divided into three or as they call it the trimester. The first trimester including the conception or the fertilization is from week 1 to 12. The fertilized egg travels to the fallopian tube and attaches to the uterus where it begins to form the fetus and the placenta. Also, the first trimester is the highest risk of miscarriage (natural death of fetus). Around the middle of the second trimester weeks 13 through 28, you may feel the fetus moving. At 28 weeks, 90% of the babies can survive outside the uterus with the use of high quality medical care. And the last trimester is the remaining weeks of 29 to 40.

In the Philippines, one in ten Filipino teenagers aged 15 to 19 years old has experienced early pregnancy. According to the 2013 National Demographic and Health Survey (NDHS) results, 8% of these teenagers are already mothers while 2% of them are pregnant with their first child. Meanwhile, among young adult women age 20 to 24, 43 percent are already mothers and 4 percent are pregnant with their first child.
