The resource I use, since i didn't know about motherisk.org, is http://www.rxlist.com. When I'm checking meds, I will look at the warnings page on rxlist.com, and see what category it is for pregnancy. Category A is almost unheard of; Category B means that there's a fair amount of experience and nothing shows any danger for a developing fetus; and Category C means that there are some signs that it's not OK, but take it if the need clearly outweighs the risk.

Categories D and X, the other two, are Do Not Take. Category X is the most dangerous, things like Thalidomide. Category D is not quite so very dire, but it's still stuff to avoid in pregnancy.

But, all this is still moot for you, until or unless a doctor diagnoses you and says that you need medication. It's perfectly possible that a doctor would recommend therapy until such time as pregnancy is no longer an issue.
