I am a parent who has bipolar and if you have a supportive partner, 'family' and community supports why not. People are parents with many challenges illnesses disabilities. It is not a perfect world. Have you discussed with your GP and pdoc. I think for conceiving and for the first twelve week trimester and breast feeding you may need to be carefully prescribed medications that don't cross placenta or through breast milk. But just as people with other medical conditions need to plan pregnancy so with mental illnesses.
Not saying it is an easy road but that is life but I also understand the choice for taking another road as well.
All the best for you whatever you decide.
