We think around 8 weeks... long story short my periods were suspended, because of endometriosis. I haven't had one since March 13... But we know as of May I wasn't prego. I took a test about the 15 of june, and it was negative. So sometime in there something changed.
Congrats to you Teri...you sound like my daughter in law, who is expecting in June. Ugh poor thing is sicker than sick. It's worth it in the end, tho.........way to go!!
