I'm currently pregnant with my 5th. I've been quasi diagnosed with bipolar 2/cyclothymia since I had a horrible postpartum experience after baby 3. Before that I thought I just had depression/anxiety issues. I had baby #4 with meds and breastfed postpartum with them and there has been no issues for my daughter. I was on lamictal and cymbalta.

I'm voluntarily pregnant again and choose to take meds. I don't tell anyone besides my husband and dr about the meds because my anxiety of being judged. But the internet is different!

I hate that people use meds as an excuse not to have more kids when certain meds have no clear cut risks vs benefits. For example, I'm on lamictal and that's a category C not proven safe but not bad. From the studies I've read, the only thing it has "maybe" done in ONE study is increase cleft palate defects .05% or something like that. Lamictal
On pregnancy websites has a very mixed review because of it. While that may mean to some people a clear cut, no way would I risk my baby, I think my benefits outweigh the risk. I think the chance of me killing myself on a regular basis would be over that without the meds. But to say no to babies because I have to stay on them? I would be horribly depressed. Yes, I have issues but I have always wanted a large family and to stay home. But I do have help when I need it and I am very honest with my husband with how I'm feeling. I think if anything this makes me a more understanding parent. Is it stress free? No. Is anything stress free? Definitely not. I'm much better with my kids/family than I ever was with working.

And who's to say you're going to be stable without having any kids? If someone told me that I shouldn't have more kids because I'm sick, that would probably make me go through an episode anyway if my choice was taken away. As it is I am extremely private about it all and barely anyone knows I have issues (that's where my social anxiety kicks in). I just brush it off, even to my kids, that I don't feel well or have a headache. But I always tell my husband the truth.

Not sure if it helps but if you have support, go for it!
I think you'll regret it otherwise. It definitely can be done and I would never take away any of my experiences! Parts of being pregnant/having babies have been the best experiences of my life.
