How to calculate due date of my baby? I am 3 months pregnant now so does that mean only 6 months left, and is there some kind of science behind calculating a closer due date?

Congratulations my dear. The babys due date is calculated medically by the simple principle that a humans gestation period is between 36-40 weeks. A baby is said to be fully able to survive outside the womb after 36 weeks. The easiest way is to calculate using your Last Normal Menstrual Period (LNMP). If it was 14-04 then you know you got pregnant two weeks after that date. Count 40 weeks from the LNMP and you have you Expected date of delivery (EDD). The EDD is always given a + or - 2weeks (i.e expect the baby any time then). You can count weeks!
Or simply add 1 Year, subtract 3 months and add & 7 days. E.g. if the first date of your LNMP was 14-04-88: 88+1= 89; 4-3=1; 14+7=21 therefore EDD= 21st January 1989

You go by the first date of your last period and add 6 days; then you add 9 months to that. For instance, my last period started on Dec 1. the Dr. added 6 days to that and then added 9 months. My due date was therefore September 7th of the following year. I actually had my baby on September 12 after labor was induced. I was in labor for 14 hours but slept most of the time. I had an epidural but it started wearing off when I was pushing the baby out. I had a 9lb 4oz baby girl. She is 19 going on 20 now and in college. How time flies!

Hi. A proper, medical pregnancy is measured in trimesters of 14 weeks each, meaning that a normal, full pregnancy should last 14 x 3 = 42 weeks. However, the average pregnancy lasts 38 weeks. It is known for some pregnancies to come to full term earlier than that without complications and the same goes for pregnancies extending past the 42 weeks without complications.

for an average, though, I would calculate in weeks, not months and work with 38 weeks.

I will actually take 10 months gestation is 40 weeks. If you do the math there is approximately 4 weeks in a month which makes 10 months. When I had my baby I thought the same thing. And it was explained to me that because some moths have more weeks than others it is averaged at 9 when it really takes ten.
