Is this something to worry about?

So 3 days ago I stayed over at my boyfriend’s house. We were having sex but I told him I wanted to stop because I had worries plaguing my mind and couldn’t enjoy it.

The morning after I started my period so we didn’t have sex but I gave him head. The first time he said he couldn’t get hard so i stopped. The second time I stopped because i started to get neck pain, I have chronic migraines and this is a sign they’re about to start.

I apologised and said I felt bad cos I know he was enjoying. He went silent and I asked if he was annoyed. He said to not start something I’m not going to finish

That felt a bit ominous and I felt a bit weird after he said that he’s never said something like that before. I brushed it off but thinking about it i don’t know if that’s something to worry about or if that’s right
