Ok so a little backstory....

Me and my bf had sex on valentines but when he pulled out the condom didn’t come out all the way so a little dripped down my ass. I tried not to panic and wiped everything away from my vagina. We were a little worried but was hoping everything was fine. Recently though I was getting nervous because what I thought was my period came 2 days late and I’ve been cramping pretty bad, back pains, diarrhea (normal for my periods tbh) but I’m starting to get nervous because I’ve never really spotted before and when I pulled my tampon out today there was very little blood on it. So I’m just curious if I’m spotting or if I’m on my period and it’s just being weird due to stress?
