Husband won't have sex with me😣

jada
So I found out in January that I was pregnant. And ever since, me and my husband have had sex maybe a handful of times! He has even straight up told me no before. I've asked him if he thinks he is going to hurt the baby in any way and he says no. But I can't figure out the reason why. It makes me feel so unattractive now that I'm gaining weight and my body is changing. And I don't know what to do! It's driving me crazy! I have gotten to the point to where I've started watching porn to please myself because my husband won't do it. He even knows that I watch it and he still doesn't do anything about it which makes me feel even worse. Any suggestions? Has anyone else had this problem?
