Struggling with Bipolar Disorder and Parenting

I am currently unmedicated for my bipolar disorder. My husband and I are trying to have our last baby. All of my phyc meds had pregnancy alerts. I am struggling with my mood swings and anxiety. I am also struggling with potty training my daughter ATM. She doesn't want to do it but she is 4. This triggers my anxiety so much because we are on a time crunch for school. I have a big family I live with but they all do their own things. I'm by myself on this. My husband works full-time and helps when he can. My irritability is out of control where it turns into anger. The struggle in my head is overwhelming.
