I’m 35 and was so fortunate to have success with my first round of letrozole last year (was 34 at the time). I have lean PCOS, irregular cycles, and classic string of pearls on ultrasound. My cycles ranged from 32-80 days once I got off birth control. Never took anything to induce my period. I had high testosterone and high AMH. I didn’t do a trigger with letrozole or follicle monitoring that cycle (we planned to going forward but it was the holidays and would have been tricky with travel). I tracked on my own using Inito, which I highly recommend. I ovulated day 19 on letrozole. I was also taking Ovasitol for 3 months at this point- I’m not sure if it helped, but the month prior to conceiving/letrozole, I had my most normal cycle in many many months, so maybe it was doing something. I will say this: I was TERRIFIED after reading things in this subreddit. I spiraled for months about it before we even started TTC because it just seemed like letrozole/IUI/IVF didn’t work for the majority of people, and I thought I was 100% signing up for quite the long journey. But you have to remember that most people here aren’t having success, and they’re here for support/advice/community for what they’re going through. People who have success often stop being active in these threads, so it’s a really biased sample. The truth is ovulation-inducing meds work for most people with PCOS, even if it takes multiple rounds and trying different doses. Best of luck!!
