help :(

Alright so my boyfriend was just eating me out. Didn't stick anything in my vagina, just messing around with my clit... Well afterwards my stomach cramped up sooooo bad I didn't know if I was gonna cry, puke, or shit. Lol it was terrible. And now the past two times I've went to bathroom, there was pink on the toilet paper. I'm no where close to my period in fact I think I'm ovulating!
