Hi, Arnagel. No decision is risk-free, but here are things to consider: On no meds your risk of a postpartum episode, including depression, mania, or psychosis goes way way up.

The knowledge that you are pregnant means that you have already passed the period of highest risk to the fetus.

You might want to ask your doc if he/she can take you off some of your meds - say keep you on just one - but that is a decision between you and your doc.

There is general expert agreement that you need to be stable in your last trimester. Your hormones are going to play hell with you during delivery and the risk of post-partum destabilization is very very high for bipolar moms. This destabilization affects your baby's health, too - if you're not stable there will be major issues bonding with your baby, with potential major long term effects.

Your concern is very valid. But don't feel you have to be a hero. Have a good long discussion with both your pdoc and family doc, get second and third opinions if you feel the need, and remember - there are no right or wrong decisions, just informed and uninformed ones.

Hi, arangel. Just reread your question and noticed you said "planning to start trying." I based my response a minute or two ago on the mistaken assumption you were already pregnant. Oops, sorry. A new consideration:

The greatest risk to the fetus occurs during the first trimester, so not being on meds when trying to conceive is a good option, one that is endorsed by Zachary Stowe of Emory University (see article). But of course going off meds involves risks to your mental health. The crucial thing is you need to be stable in the third trimester for reasons I list in my previous answer.
