Thought my period was over 😭

Alright so this weekend I went to my boyfriends house. I thought my period was over, I hadn’t bled all day so we were down to have sex 😂 we had amazing sex, everything’s fine. THERE WAS NO BLOOD. But about five minutes after I got outta bed and there was a kinda big spot of blood on his sheets 😭 my period re started smh. I was kinda embarrassed at first but he was super chill about it and understood
