Cramping after intercourse?

So, my husband & I had sex yesterday afternoon. It hurt a little bit so I don’t know if he was just being harder than usual or what was going on. It wasn’t painful, just uncomfortable. When I went to the bathroom afterwards I noticed the tiniest amount of blood. Ever since then I’ve had this cramping type pain in what I can only imagine being my cervix. They feel like period cramps but more achy. My period isn’t due for another 2 weeks so I known it’s not that.

Is this something I need to be concerned about??
