Extreme cramping and pain?!

Mariah

We had sex about 45 minutes ago. Doggy style to be exact. Idk if this matters or not so sorry for TMI. After he was doing my cervix started cramping extremely bad and sending a shooting pain down my vagina. It’s still cramping but not *as bad* right now. Im 7DPO. Did I just hurt my chances getting pregnant? Has anyone had this? Please help.
