Hi all I am 44 and started letrozole for the first time yesterday. Haven’t felt anything other than the odd twinge here and there. I have been TTC for almost two years. Fertility specialist had myself and my bf tested and we are both good. My numbers are normal for my age. I am going to try this medication without IUI for this month and February. And if that doesn’t work then on to IUI. Would love to hear your stories and if you had success or not being on letrozole. I take 5mg a day for 5 days on CD 3-7. Today is CD 4. I used opks before this and pretty sure gotten positives but did not get pregnant so hoping his is the boost I need.
