How many days in a pregnancy after conception?

Answer 1

A full term human pregnancy is to 259 - 280 days or 37-40 weeks. This is calculated from the first day of your last period, so to be more accurate, if conception took place 14 days after the first day of your last period, you need to subtract 14 days from the 259-280 days. However, the way the medical community gages it, a woman is considered 2 weeks pregnant the day she conceives because they chart the pregnancy from the first day of the last menstrual cycle.

Answer 2

245 days if you make it to 37 weeks LMP known as “early term” or 35 weeks post ovulation or (34 actual weeks of Actual pregnancy 1 week post ovulation when implantation occurs). 252 days if you make it to 38 weeks LMP or (36 weeks post ovulation or 35 weeks of actual pregnancy/implantation 1 week post ovulation). 259 days if you make it to 39 weeks LMP or (37 weeks post Ovulation or 36 weeks actual pregnany considering the embryo implants around 1 week post ovulation). 266 days if you make it to 40 weeks LMP or (38 weeks post ovulation or 37 weeks actual pregnancy from embryo implantation approx 1 week post ovulation. This is 8.8 months or a little over 8.5 months for 38 or 39 week “LMP” dated pregnancies.
