worried please comment 😓

I'm 8 weeks and 2 days pregnant. Me and my boyfriend had sex and he wasn't going too deep but he was going a little bit fast. When we got done having sex I was having a little pain in my vagina but I'm not having pain in my stomach or nothing. I'm not even bleeding either. Just a little pain in my vagina that's it. 
Is something wrong?? Will something bad happen to the baby?? 
I regret having sex while pregnant now 😓
