Comment plzzzzz

Me and my fiance had sex today... I'm 38 weeks & 5 days.. Well anyways we had sex and it was pretty intense and hard/rough we haven't done it like that in awhile...

Now I'm feeling a lot of pressure on my back, it feels like the baby is laying on the top of my butt cheeks and a lot more pressure in my lower area.

My baby has been head down since 25-28 weeks.

Kinda cramping now also... But I'm not dilated or anything At all....

Why am I feeling this??
