I’m SO embarrassed!

So not a question per say but long story short. I had made plans all day to go over to a guys house tonight. We haven’t hooked up for a while now so I was very excited. We had been sending pictures this evening and then I go over. And just a few minutes into the actual thing he noticed my period started back up again. He literally goes “oh shit” and stood up walked across the hall to see in the mirror. Then asked if I was on my period. I was mortified! He said it was okay and that he would take care of it. He just wanted to go shower. And I got dressed and left. I am soo embarrassed and I don’t know what to do!😩 💀😭
