I want a baby

We had a miscarriage in December. we tried right away but were still ify on whether it was too soon.Now we are trying and I'm trying to eat healthier and get more exercise in. I'm 26 and 235lbs. Have any of you had children. being plus size and close to my weight? My husband is very supportive and says we got pregnant once WE can do it again. I'm just nervous, as any person ttc. Your advice or personal experience would be appreciated !!! Baby dust and love to all of you!
