Losing weight to have a baby , is there a group ?

So , I am currently 235 & my husband and I have decided to start trying for a baby . I really don’t want to be this weight and get pregnant because I would actually like to look pregnant and not just fat . ( I am saying this about myself) is there any group that is dedicated to this ? And I’m not a skinny girl who thinks she’s fat , I’m actually a fat woman . Thanks
