Painful intercourse

I had intercourse on the 24th and it was kind of painful, usually it doesn't hurt! It felt like he was hitting a wall or something (I assume my cervix), well afterwards I went to the bathroom and when I wiped there was pink spotting. I didn't think much of it so I went to bed, I woke up with bad cramps and the pink spotting had turned to light bleeding, so on the 25th it was still light bleeding when I went to bed, and now today and yesterday it is brown on the pad but dark red when I wipe. Is it possible I'm pregnant and my boyfriend was hitting my cervix because of it?
