letrozole

Rachel • I'm 35years old. Happily married military wife. Have been trying to get pregnant for about 3.5 years and have now been confirmed pregnant by blood test. Due Feb 2020

I have taken it 3 times to help with pcos. the first time in Sept with an iui. they wouldn't do another iui till my husband's count went up. So I just tried it Oct and Nov with tines intercourse. the 1st two times I took it my cycle was my normal 31 day cycle this last month I took I just started my cycle a week early making a 24 day cycle. This is early. I thought letrozole was supposed to regulate you. Anyone have thoughts on this?
