Thank you Dr. Norm for your answer.
What other treatments do you think could be suitable in my situation? I'm in the UK and I'm told the maximum dosage for Clomid is 150mg so I don't think they'll increase the dosage.
I've been taking metformin 3x500mg since I was diagnosed with PCOS 15 years ago. So far, it hasn't helped me in conceiving my second child. I was able to conceive my first within 3 months of trying. But I had regular 40 day cycle and weight 50kg as mentioned.
I'm inclined to believe that the complications are aided by my weight gain.
I have an appointment with my gynaecologist tomorrow so I will discuss gonadotropins as an option with them. Thank you for your help!
