Guys, what would you do if your girlfriend bled through on your bed while on her period?

I was there for the night and I had told him we can't have sex because I am on my period. I was wearing a pad but I am a heavy bleeder so I had bled through. He woke me up in the morning all upset about me "making his bed look like a murder scene". He acted like I did it on purpose. I was so humiliated. I get that it's gross and sucks but it's not like it was my plan. Now he's acting like it never happened which is weird and I kinda still have sad feelings about it. Would all guys react like that? Because I am getting unsure of our relationship. If it was the other way around the last thing I'd do would be getting angry about it.
