HELP! (Kind of tmi)

So im 12 weeks pregnant and my significant other and I just had sex for the first time in almost 2 months. He came in me and after when I went to clean myself up found that it was a pinkish tinge. He has a very large you know what and I'm scared if my little one got hurt? Maybe my cervix is just sensitive right now? I am not in pain but my vagina feels a little raw. Please help of you know anything about this or have experienced this. So freaked out.
