Alot of very bad advice
The person who was talking about tetnus is wrong, tetnus isnt caused by rust, ti is caused by a BACTERIA.
One person told you to use aluminum. DON'T, unless it is hard anodized and even then I wouldn't use it if I was pregnant.
On persid said the nonstick was paint. It isn't
You mentioned it was non-stick. The teflon coating is supposed to be biologicly inert so the flakes of teflon itself are not dangerous, but gross. But if you raise the temp of the pan teflon "outgasses" and the gas IS considered poisonous. I agree with the poster named john holmes, why risk it?. I'd just throw the pans away or give them to goodwill. I would use teflon pans or cast iron only in moderation while pregnant. I wouldn't refuse to eat food cooked in it, but I would avoid it at home. I would use mostly stainless or enamel coated steel.
