my friend who is bipolar 2, went thru her pregnancy just fine without meds but immediately went back on her antidepressant after breast feeding failed.
She had gone off a lot of meds to initiate their fertility tests etc.
so she wasa given all kinds of hormones and she made it thru it!
I would encourage you to try on your own.
May I ask...you are on 2 anti depressants?
that doesn't swing you into mania?
glad that the topamax is working for you.
Also You sound like a wonderful couple and would have wonderful children...smart funny and creative like yourselves.
