strange question about sex and IUDs

Sam

I have a somewhat strange question. I have had my IUD for 8 months now. I just had sex with a guy with a very large penis (9 inches and super girthy.) there was no protection (both clean) and he came inside me. I bruised my cervix and it hurts. There was a little bit of blood. Is there a way for me to get pregnant from this? My period ended 2 days ago. Anything would help. I'm just kind of anxious about it.
