i had had unprotected sex about a little over a week and a half ago which lasted about 5 min. when i found out he wasn't wearing anything and during that time i was still kind of on my period and about a week after i had gotten my period again. i feel perfectly fine except every once in awhile my stomach feels like it would if you were on a rooarcoaster ride because i think i think about it too much, any advice would help.
