TMI 15.6 weeks pregnant bleeding

Jocelyn💋 • Have a wonderful life that I have to thank the Lord for❤️ have a son and expecting baby girl🌹
I just had sex doggie style, and it was rough and I felt like he was hitting my cervix, after a few thrust, I got on top which felt better meaning it didn't hurt my cervix. After that he fingered me (sorry this sounds so dirty) and I orgasmed. Well I went to pee and I noticed I started spotting. I am wondering if he might of cut me while fingering me or if doggie style had anything to do with it? It's not a lot of spotting but it's enough to make me ask this question. Thanks in advance.
