What Is My Conception Date If I Am 28 Weeks?

You have not indicated your first day of last menstrual period because pregnancy is calculated from that day. You can calculate your possible date of conception by adding 2 weeks in the fist day of last menstrual period or by subtracting 26 weeks from now. These calculations work if you have 28 day cycle and ovulated at mid of the cycle. This will give your approximate date because exact date of conception can not be calculated due to ovulation at different times of the cycles.
