Letrozole 2.5mg

Vid

Hi ladies , we just went to see the fertility doctor for our blood test and semen results. Doctor said we dont have any issues. Just that my period is abit longer now like 31 /32 days. So she prescribed Letrozole 2.5mg for Day 2 to Day 6 of period. Is letrozole good ? Does it help ? Anyone got a BFP after taking letrozole ?
