So, have anyone had sex when they thought the period went off....

So my bf was getting extremely horny and initiated the sexual encounter. I told him that it’s off but I really wanted to wait until it’s in the clear you know wait a couple days after...even though blood wasn’t present the same day... any-who my fine ass man was like babe I want some of you and I’m like in my head me too.... I told him to wear a condom of course because you never know..... so in the middle of the sex session I feel something I thought sweat 😓 but I told him to stop because something felt weird... so I rushed to the bathroom and saw blood..... 🤦🏾‍♀️🤷🏾‍♀️ it wasn’t a lot but enough for me to get bothered... My boyfriend was like it’s fine.... I was totally freaked out but it felt good but oh well.... so I rushed to our bed to check I saw some spots so threw the comforter in the wash machine... Have something similar happened to anyone if so what was you or your partner reaction....
