As the result of a drunken fumble, and probably only the 3rd/4th time we have had sex this year (usually one of the kids in our bed) baby f #3 is on the way. Had sex late Friday 16th Sept. tested 2 weeks after that with a clearblue and it was negative. Period a few days late now so tried 3 different tests today and all positive. So I think my husbands super swimmers were alive up there a few days before egg drops. I usually get bfp at 10dpo. Not 18! Not got my head around it yet. Thought we were finished having kids.
