Yes and yes.

It is dangerous for the baby to take your medications, however, it is EXTREMELY dangerous for you to go off them.

When you are bipolar, pregnancies cannot just "happen". They need to be planned out in order for the doctor to put you on prenatals and vitamins to help with a healthy baby. My doctor says I cannot go off meds while pregnant, and even though the meds can affect the baby, there are ways around it but cannot necessarily be 100% preventable.

Not sure if that made sense, but I would not jump into a pregnancy while bipolar.
