I got my period... during sex

Me and my boyfriend were having sex. He got me to come. He pulled out. And when he left the room I put my hands downstairs. There was a brownish orangish mixture. It was clear and really weird. I thought it was my period. But we also used orange lube so I wasn’t sure. I told him and despite him being a stupid male who thinks periods are the grossest thing, he was really nice about it. He said he didn’t think it was gross because I didn’t know. When I got home it revealed that my suspicions were correct. I got my period
