Does weight , weigh against pregnancy that much?

Is there any other “bigger” women on here worried that they can’t conceive ?

I weigh 246 (5’7) (used to weigh 259 )

but I started working out more to boost my health , I just feel like I keep hearing my weight won’t let me get pregnant :/ ?

Any other women who are going through the dance thing? Has anyone over 200 gotten pregnant here? Any tips?
