Sorry to ask but what is it that is happening when you have sex? Just that bit of info is missing and it might help other people answer your question.
If it is bleeding that is happening yes this happened to me as long as you are not experience abdo cramps or any other type of pain in you abdomin and the bleeding is not heavy then I think it is normal after sex bleeding that can happen dueing pregnancy but if it is heavy or you have any pains in your abdomin I would get it checked on the safe side
