Healthy way to lose weight while pregnant?

La

Hello all, recently found out I’m about I’m a couple weeks preggo 🙌🏼 For the last year ive gained loads & I’m now medically classed as overweight 😭 I want to know if there are any healthy & safe ways you pregnant people have lost some pounds to ensure your baby doesn’t have any complications during pregnancy. I also get bad chaffing where my legs rub together when I walk which can be painful & I can only assume that it’s going to get worse if I don’t do something about it 👎🏼

EDIT: I was size 8 & am now size 12 (UK sizes) & doctor has recommend it & said it was safe as long as I eat healthy & am not “dieting” which I’d never do.
