May PCOS ako kaya kailangan ko ng assistance from OB to get pregnant.

I had my period last April 6-10, 2022. Pinagtake ako ng letrozole to ovolute. If conception was not succesful, I will be having my period. Expected date should be May 4, 2022. I know its possible that I might pregnant but hesitant to take pregnancy test due to negative results in the past. What will I do?
