My father keeps pointing out my weight gain.

I’m 36 weeks pregnant. My dad has been making jokes about my weight and the size of my belly for a while and it’s finally getting to me. I’m 160lbs now and I started at 125lbs. So that’s only 35lb weight gain and the baby is at least 5 of that. Not that any of that should matter because it’s natural to put on weight while pregnant, but really he’s picking on me over a reasonable weight gain? Ive always been at least slightly underweight so he should be happy I look healthy, but today he told me I need to burn off some fat. He always makes it out like he’s joking, but makes those “jokes” every single day like calling me tubby or chubby or pointing at me and laughing. I’m balling my eyes out right now cause I just feel so shitty, but idk what to say. I know I need to tell him what’s up, but when I get angry I just cry so it makes things awkward.
