Very faint pink spotting after sex?

I’m currently about 26 weeks pregnant. My whole pregnancy I’ve experienced no bleeding at all after sex. This time, I after I wiped there was the faintest pink spot..it was almost nothing. I freaked out a little and wiped again, a little more this time but still very faint. It was gone on the third wipe and I went to the bathroom shortly after multiple times and nothing, I also put a pad in for about an hour after. Again, nothing more. I’m thinking maybe I got a cut down there or something? I know friction and rushing things can sometimes be irritating but this has NEVER happened to me. I’ve never bled after sex even pre pregnancy unless I was finishing up a period.
