Smurphy, may I ask if you were checked out for your thyroid before they made the bipolar diagnosis? I ask because thyroid problems can mimic bipolar extremely closely and hasn't been uncommon for misdiagnosis to be made before. Not saying they misdiagnosed you, but I am curious.
I was misdiagnosed with bipolar years ago but it was due to a rubbish psychiatrist who didn't listen or look at my history.
I didn't take any meds with my first child, with my second and third I took diazepam on and off, because of anxiety. They did offer me various other things but I refused because I was paranoid and didn't trust anyone, but to be honest I don't think I actually needed what they were offering me anyway. They were antipsychotics, and I didn't need them. Taking diazepam isn't ideal in pregnancy, especially during the third tri because of dependency and baby can obviously go through withdrawal, but my children thankfully didn't and I think this was due to me not taking them like clockwork - only on an as and when absolutely necessary basis
