Pregnancy and mood disorders

When I was 22 I was diagnosed with Bipolar Disorder after years of depression treatment. Of course, being pregnant I can’t take any medications (not that I was anyway). The past couple of days I have been so depressed I don’t want to get out of bed. I can’t stop crying. I’m irritable. I haven’t had any mood swings during my pregnancy. I’m 23 weeks. Does anyone have any recommendations to help with this? I’m seeing a therapist but my next appointment isn’t until next Friday. I just want to feel happy and excited like I should. It’s very discouraging...
