Period problems πŸ˜’πŸ˜‚

I was in my Boyfriends house and I thought my period had ended the day before, I checked before I went over just to make sure and I had no sign of spotting or anything!Β 
So then later we got down to business πŸ˜πŸ‘…πŸ’¦πŸ† and everything was fine. He then fingered me and stuff about an hour after.
Then he walked me home and he told me I was bleeding and he showed me the side of his hand... I've never been more embarrassed in my entire life! Has this ever happened to anyone else? πŸ˜‚ #periodcockblock
