Would you be mad?

Okay so I'm 27 weeks pregnant and a majority of my pregnancy I've had no sex drive but the past month my sex drive has been back to normal. In the past month I've had sex once but otherwise I've been basically begging for it. I've been very self conscious this pregnancy as I started off larger than I did with my first and even though I have a fairly noticeable baby bump I feel like everything looks terrible on me and I just look fat but my husband assures me he still thinks I'm sexy. Today I walked on him masturbating. Normally I have no problem with him masturbating and I occasionally do it too but I'm honestly pretty upset about it just because he won't have sex with me lately and he knows how self conscious I've been so I feel like maybe I'm right and he doesn't find me attractive right now. How would you feel in this situation?
