help!! medication need advice

Hey everyone I'm seeking some advice, I'm bipolar and I stopped taking my medication (serquel) when I got pregnant,  my doctor said it was up to me and if the bennifits outweighs the risk I could take it. Well I'm 20 weeks and up until about a month ago I was ok, now I see my dangerougs patternes emerging, overwhelming sadness, anexity, migraines, not exactly taking proper care of myself, and I'm considering taking the med again. Google says there are no human studies with that med. so what would y'all do? Or is there anyone taking serquel while pregnant here?
