Short LP and letrozole

Sofia • 👶Nov 2019, 👼 April 2021 🤰Aug 2022

I’m starting my first cycle with letrozole/femara. Has anybody had any luck with this medication? My LP has normally been 7-8 days. Had a chemical just before New Years and last cycle my LP was 12 days but no bfp. This is our 7th month ttc.
