have you gotten your thyriod checked? i didn't til this last summer2002 and the reason i gained the weight that i did is because my thyriod is underactive. go to an ob/gyn and ask them to do a full blood panel including your hdl and ldl and cholesterol that way you can find out if there is something keeping you from getting pg. i hardly think that it is because of your weight. considering that this is the first time i have ever heard of it being used as an excuse to not do tests to find out the real reason. call your local hospital for a referal to a good ob/gyn. if it hadn't been for mine then i wouldn't have found out on a lot of my health problems. if you need any more info feel free to email me at tklarimore@yahoo.com.
sincerely,
a person that a nurse practitioner told me that i could die if i had a baby at only 250 lbs. ob/gyn said he had delivered babies from moms that were 400 to 500 lbs.
