Pregnancy and overweight worries??

Does anyone else stress about being overweight and just becoming pregnant?? I'm 22, and I weight 170-175 prepregnancy (I'm 5' 2"). My biggest concern is having a miscarriage and I know being overweight can increase the chances of it. But theres not really anything I can do now about it since it's not healthy to lose weight in pregnancy. I was in the middle of trying to lose weight when I got pregnant. Just stressing a little 😣. I can take all the nausea, sore boobs. Etc.. it's just the worry about this baby that kills me. I'm almost 8 weeks, but I'll feel much better when I get way further along.
