I 27F am 8 months pregnant and find myself devastated over my husbands 31M porn use

Basically what the title says, I 27F found porn on my husbands 31M phone while swiping through apps to send some pictures from his phone to mine and I feel so horrible about myself over it. I’m 8 months pregnant and I feel guilty over how difficult it has been for me to engage in sex because I’ve been in a lot of pain and exhausted and generally not feeling good. I feel extremely sensitive about how large I am right now compared to what he’s watching. I am sure it’s partially the hormones but it feels existential, I can’t stop thinking about it and crying by myself and I can’t bring myself to talk to him because I feel so embarrassed and afraid of starting a fight over something that I am reading is “normal for men to do”. I get it he’s going to want things that aren’t me but how do I stop feeling like I’m dying over it? I find myself wishing I wasn’t pregnant again and that I’ll never look like those girls again and I just feel really really badly even though I know it’s not right. I don’t know how to make it feel okay even though the general consensus on the internet seems to be that all men are going to watch porn that doesn’t look like me and that’s okay.
