Today I got a positive pregnancy test as a result of a 5-day frozen embryo transfer one week ago (on 2/2/2023). It looks like a typical pregnancy is 266 days from fertilization to birth. Based on these numbers, my own calculations and several internet calculators put the due date at Oct 21st, 2023, but of course babies often show up early or late. It looks like the earliest recorded successful birth was at 132 days gestation and the latest at 375, which are pretty close to 266*.5 and 266*1.5, so I've rounded to those for my upper and lower bound. I was born June 3rd, 1988, am 5'7" tall, and weighed 214lbs when I weighed myself yesterday. I have no known health problems that would affect pregnancy.
