Ovulation? Could I be prego?

Question

I never really figured out when I ovulate. I kept track of my cycle for a year and it was different every month, ranging from 21-28 days. It's not unusual for my period to be a little late. My question is, if my last period started on Aug. 5 and I had unprotected s*x on August 31 and September 3, could I have been ovulating at that time? How can I use the "rhythm method" effectively? Also, if I am pregnant, in order to figure out my due date, is it true that I go back three months from the first day of my last period and then forward one week? For example, my period was Aug 5 so the baby would be due May 12?

Answer 1

I highly doubt you would be ovulating. You ovulate 14 before your period is due. As far as calculating your due date, you count 40 weeks from the first day of your last period. So yes it would be May 12, interesting calculation method...never heard that one.  

Answer 2

Hi there

Your most likely to ovulate on the 13 14 15 16 17days after your first day of bleeding.

So for example if you started your period on the 5 aug you ovulating days would be the 19, 20, 21. But that's not to say that you could still not have fallen pregnant.

Good luck xx
