My last period was Mothers day of this year (05-08-2016) I had sex around 05-14 to 05-19 everyday unprotected with my fiance (trying to conceive) Dr says I conceived on 05-22-16. I also had sex on 05-23 with a condom, no ejaculation. I am trying to figure out which day would make sense that I got pregnant. My due date is 02-12-17. Just nervous and anxious need advice. Also around 05-20 I had the worst cramps. So bad I was nauseas and couldn't stand.
