My boyfriend and I had sex on July 1st, and then again on the 2nd. I am pretty sure I got my period later that evening on the 2nd and by the 3rd I was pretty sure I had my period - all systems go. BUT on the 3rd my boyfriend asked if I had found a "lost" condom - from our sex on the 1st. I said no and wondered if this was something that happened regularly and then dismissed any further thought... Well, on July 5th I "found" the missing condom - it had been inside me the whole time and I didn't know. We had sex once while it was inside me and I use tampons for when I get my period. My period seemed normal enough, but after my body expelled the condom the next day my blood was a little brownish... Now it is 28, possibly 29 days later and no period, no signs of it either. I am pretty regular. I have been pretty stressed over this since July 5th and my anxiety is over the top now that I am late... I have taken two pregnancy tests and they both say I am not pregnant but everything I have read doesn't really reassure me, at all. I have a breakdown once a day and the "later" I am the worse they get. Any advice or answers would be greatly appreciated.
