Talk to Gynecologist on Conceiving

Hello, need guidance from doctors and experienced people. I have PCOS and got checked up with doctors and they said it’s not severe. I am having 35 days cycle and flow is normal. It’s been 4 years to my marriage but initial 2 years we were not together. I went to fertility specialist and she asked me for all the primary fertility tests and all reports were fine. She suggested to go for Ovulation Induction cycle and i took it in last week of august. Later in 2019 September i conceived and in October I went through miscarriage. Later in February I again went for the 2nd cycle and that time was no luck. We have tried naturally but there’s no consistency and I don’t know whether I can conceive or not with PCOS. I have no other medical condition. I want to conceive and i am thinking to take only Letrozole tablet in my next cycle from day 2 for 5 days. Please guide doctors if I can only take table not a complete cycle.
