So we moved on 7/15 and I was supposed to start my next pack of BC on 7/16. I let DH know. He previously wasn't ready to start trying - but he didn't balk at DTD w/o protection. Well since we aren't officially trying, I haven't been keeping a log of when we DTD but I do recall 7/23.... which would be CD 14. Now normally I O on CD 18 or so... but maybe coming off of BC my body is more on the 28 day track. So over the weekend I've been having lower back pain and am obsessing about if I could be PG. Really? Really? We're not even trying yet and I'm already obeseeing!?
