Hi doctor moms if i am due aug 29 i got pregnant from sex in december?

Yes: Your last period would have been about november 22 and you would have ovulated about dec 5th making your due date about august 29. You could have conceived about dec 2 through dec 10.

After December 6: Naegele's rule is a standard way of calculating the due date for a pregnancy. The rule estimates the expected date of delivery (edd) by adding one year, subtracting three months, and adding seven days to the first day of a woman's last menstrual period (lmp). The result is approximately 280 days (40 weeks) from the dlmp. Ovulation is 14 days if you have 28 day cycle. Reverse the formula.
