It's one thing to be on a drug and get pregnant- then decide, along with your physician, if it's safe to take while pregnant. Unless you're leaving out some information, I find it interesting that you're posting this while now full term- a little late to be asking, isn't it? Some drugs are rated category X- should not be taken while pregnant as they can (and most likely will) cause birth defects. Category B is often used, and is mostly safe- Category C is more restrictive- will depend on physician and if benefits outweigh the risks. Most drugs these days are only approved as Category C, and upgraded only after they're on the market and LATER upgraded to Category B. The reason is it's harder to do studies in pregnant women while still in trial phases, before they come to market. Others below mention Zoloft and other antidepressants- however be careful, as this is not the same class of drug (and not all drugs in the same class have same safety, etc). Bottom line is, discuss it with your doctor.
