Talk to Gynecologist on Want To Conceive

I have a daughter who is 4 years old. I conceived again in june 2019 and it was a blighted ovum pregnancy which I was told is a missed miscarriage. From then I have been trying to conceive but havent till now. In sept 2020 I was diagnosed with pcos as well. I consulted my gynaec in jan 2021 and she asked me to come on 12th day of periods. There she did a tvs and found that there was no ovulation. Then she called me on first day of periods. She asked me to get FSH and prolactin tests done and they came out normal. Then she advised me femara tablet for 5 days. 1 in morning and 1 evening. On 6th and 7th day she has asked to get injection. I wanted to ask are we on the right path? Today I completed 5 days of medicine. And have to go for injection tomorrow.
