Heyy guys just needing some opinions or something ..

I’m currently 345 and found out I’m pregnant with baby number 2 !! My husband and I are so happy to have another baby we planned it . But I’m soo discouraged because of my weight and I’m scared of how big I’ll get through out my pregnancy . This is the biggest I’ve been and I wanted to lose weight before I got pregnant but we just decided our want for a baby was stronger then me losing weight . My family all says the same about I should have lost weight before getting pregnant again or I’m to big to be pregnant .. I just feel discouraged and I’m dreading my first appointment cause I know I’ll get talked about for being so big and pregnant by my doctor and I always feel judged . I guess just posting for advice ?? If it’s the wrong place to post I’m sorry
