Need advice..is this true?

I was telling my friends and family that we are starting to try and a lot of them looked down on me and seemed concerned because of my weight.

I have been told by multiple people that being obese causes increase risk of Down syndrome, Autism or other birth defects

I actually had a “friend” tell me that every person they know who has had a child and is obese their child has Down syndrome or some other form of a birth defect

I tried doing some research on this and it does appear there’s a increase risk compared to non obese people.

I’m very nervous now. Please help
