So I had sex last Wednesday, first we started off with a condom, then he took the condom off so I could give him head, he went soft, forgot to put the condom back on & went back in, he nutted(WHILE HE WAS SOFT) idk if he nutted in me or not but today my butt was burning & I went to use the bathroom, my pee was normal, when I wiped from the front there was this little brownish kinda pink not really spot on the toilet paper & when I wiped the back there was a lot more....am I pregnant? Although I'm still ovulating & my period won't be here til the 3rd of June & we just had sex a week ago....do I have something? Someone help me plssss
