Plus size pregnancies??

I am 240 lbs and 5’10. My weight is distributed fairly well but a close friend of mine keeps saying I need to lose weight when I’m TTC. I work out every day and eat pretty healthy. I have a thyroid problem. She’s saying it because she’s 5’1 and 200 and her doc told her that but her weight was all in her stomach.

I just want to know is anyone out there as big or bigger than me and succeeded with TTC? I need some positives.
