so...for about 2 weeks i've had some kind of breakthrough bleeding while on BCP. I did have a water sono and an endo biopsy within those two weeks, so i'm sure some of it relates to that, but its so weird that i have bled this much! Yesterday (my last day of BCP) it started geting heavy, so i thought i was getting AF, but then it stopped, and now today i've hardly had any bleeding and i dont feel like AF is coming.

I know this sounds weird, but could i not get AF because i've bled so much already? I am supposed to go friday for my first blood and sono for IVF, but i'm concerned that i wont be able to start my injections because my cycle is screwed up.

anyone have thoughts or an experience like this??
