TTC and bipolar

I'm 35 and my hubby and I are TTC for the first time.  But we aren't even quite there yet because I have bipolar (mood disorder) and I have to change all of my psych meds so they are fetus-friendly.
That has to go smoothly for at least 1 month before my IUD is yanked and we go live.
I'm just worried that the longer I'm off my usual meds there will be an increased chance of going off the rails. Again.
Has anyone else gone through this.  A lot of my friends are moms, but none bipolar, and all of my bipolar friends can't/won't have kids.
 I'm feeling a bit alone here.
