Spotting after sex...

I’m 11w2d and we had sex last night. I spotted afterwards and I’m not sure if I should be concerned. It was light and has stopped. I should mention that this isn’t a new thing, it’s happened nearly 80% of the time we engage in said activity. The doc checked me about about it last year and said everything looked okay, but now that I’m preggers obviously it’s concerning. I was reading that it’s fairly normal for pregnant women to experience it based on the cervix being sentisitve and extra blood flow. Does this happen to anyone else?
