blood after intercourse?

Hey mamas-
I had a very very light, small amount of blood occur after I had sex. It wasn't even a enough to drop into the toilet, only a very tiny drop/smudge when I wiped and then stopped after I wiped a few more times. Is this normal? Sorry, this is my first pregnancy and everything scares me. I haven't gone to an OB yet due to me not being 8 weeks so I don't have a doctor to call and ask. 
Sorry, and thank you!
