TMI- sex brought my period early 😩

So me and my man were taking our time on each other and enjoying the moment. I wasn’t supposed to start for 5 more days.. well an hour and a half or better when we were finished I went to shower and once I finished I came to bed so he could go get a shower. He ran back to the room to ask me if I was ok.. I was like yeah why and he said look. There was blood all over both his hands, his 🍆, and his face 😱😳 Clearly we were so caught up in the moment we didn’t notice. I was embarrassed bc neither of us noticed, smelled, or tasted anything and of course we had the lights off.... are we the only ones who have had this happen...?
