What should I do about my husband?

So before my husband and I got married I was really trying to work on my weight. I have always be large , no I’m not going to say chubby or thick I’m plan down right fat. Anyways I was getting to a point where I was accepting myself... then I got pregnant and had two miscarriages and gained weight... my husband who was my boyfriend at the time asked me to marry him... I said yes Ofcourse but immediately I was like okay I’m gonna get in shape and work out to look great in my dress! So I hardcore dieted and nothing happened I ended up gaining weight and was really upset and cried... welp low and behold I was pregnant again! I was happy but scared... we got married when I was 7months pregnant getting larger after the wedding ... I gained 60lbs or maybe more... I have lost some of it but since the baby I have looked at myself and I’m HUGE ! So again tried a diet and was watching what I was eating but with a baby... welp in May I found out I was pregnant again! Now I’m gaining weight on top of the weight I have already put on... yes if you’re still reading this has become so bad my husband doesn’t even want to have sex with me anymore. I asked if it was because I’ve gotten so large.. and he said he didn’t want to hurt the baby but he was never worried about it before... I’m not sure if I could feel any lower... can I workout can I loose weight while I’m pregnant? I thought about not eating so much and going to the gym try to loose some weight.. I don’t want my husband to be disgusted with me... what should I do?
