how high risky is it to be plus size and pregnant??

Hi ladies, a little about me ...I'm 26 yrs old , I have a beautiful 6 yr old daughter . my weight that I started at with my daughtets pregnancy was 139 lbs and ended at 175 lbs . and ever since I never lost weight and I'm 221 lbs now !! 😞 ive had 2 miscarriages, the last one was in May of this year . and last night I got my BFP

but I'm just scared if ill have another miscarriage because of my weight . My DH is worried for my health and recently had a friend who died giving birth and he just feels like I should lost a little weight so I'm not with a risky pregnancy . anyways idk what to think ...please give me some opinions . I wouldn't want to risk my life
