Did you taper off slowly or just quit cold turkey? This is too late to be said, but this is something to be done before you get pregnant so you have time to taper off slowly and avoid withdrawal symptoms. I'm a guy so I've obviously never been pregnant, but the reasons to not take the meds is to avoid birth defects and to avoid having a baby born with a brain on meds. As to the rest of your questions, they are best directed at your obstetrician, assuming you have one who talks to patients about such things.
