Pregnancy sex...feeling less attractive especially after this argument...Advice please?

I’m currently 27 weeks pregnant and I will admit some days I’m so tired I can’t have sex with my husband but I would never “reject” him if he tried to have sex with me. My husband usually goes for a run in the mornings. I didn’t realize he was going this morning because we were talking for a while and I got the impression he was staying in. This morning I was feeling better and I wanted to have sex...he was very aware that I wanted to have sex. However, he told me he’s going for a run because he didn’t run yesterday. I mentioned we also didn’t have sex yesterday or the day before but that doesn’t seem as important has his morning run. He told me he didn’t see anything wrong with going for his run returning and going to work. He told me I should be supporting him running to stay healthy which I always do. This was the only time I happened to be horny the same time he decided to go running. Most of the time I don’t interfere with his morning run. Although I was laying in bed ready to have sex and he basically rejected me to go running instead. I’m already struggling with lack of affection from him I have to ask for more hugs too. I just wish he reached over to touch me and hug me without me asking him to. I feel so big right now; my weight has increased so this makes it even harder for me. I don’t feel as confident and beautiful while pregnant but maybe if my husband really showed me that nothing has changed and he’s still very much attracted to me I wouldn’t feel as bad. He told me it was crazy how I was acting this morning. While he was running I was in the bed feeling unwanted and emotional; I found myself in tears but had to get up to get my son ready for school. Sometimes I feel so alone due to the lack of physical affection even though he’s right here. Did I overreact? Any advice?
