Frustrated again.

I called my doctor today because I don’t think the clomid is working. I know it could still happen but I am not ovulating I asked if it doesn’t work this month if we could up the dosage bc there is a max that you can try this drug for. And I have done tremendous amount of research. And most people I know or have read get monitored while taking this drug like atleast bloodwork and ultrasounds and I’m not. My doctor just sent me home and said good luck. They told me no. That they would keep me on this dose and I just wonder if I should switch doctors. What’s your opinion?
