Last month, it took 21 days to get 1 follicle. I was in 5mg letrozole. This month, they doubled my dose, and I had killer headaches and the day after I stopped taking them I was a crazy lady. I would have totally been ok with it, if it worked. Today is CD13 and I went in and had only 10-12mm follicles!!! And my lining is only 4. I don’t even know what to do... I feel like this is just a bad circle of bad luck. I go in again Friday to check my lining and follicles but I’m feeling defeated.
