Pressure down below during pregnancy?

Emily

So my man and I had sex last night. And now I have a lot of pressure/cramps down below and it kinda goes into my butt. I’ve had these cramp like feelings before during a period. But is it normal during pregnancy ? I’m 2 months along. I thought I would sleep them off but I woke up and the feeling is still there. Has anyone had this or know what I’m talking about ? Help! Thanks :)
