TTC but got a lot a weight to lose(100ib) any suggestions?

Always been a big girl, but I’m trying to conceive and I think my weight is coursing the problem, I need to lose around 100ib to get to a decent goal! Any recommendations and tips would

help!

Also I’ve spoken to my doctor, they haven’t said it’s the problem but could be the reason I’m not falling! Also be referred to dietician, but due to the pandemic unable to be seen untill after everything has calmed down and wanted to try and get started now!

Thanks 🤞
