spotting days after sex?

Hey ladies. So I just had sex 3 days ago with a new partner after not having had intercourse in a couple months. Note: he had a little more girth than the last partner and initially hurt when we started it kind of felt like he was stretching me. The pain subdued after and was able to enjoy it. Now the next day I noticed that when I wiped there was a little bit of blood, was mostly pinkish and realized I was spotting and have been doing so these last 2 days. Is that normal? I'm not due for my period until 2 weeks from now. Thoughts?
