Fertility pill

Kandice
Anyone took letrozole? I took it with my cycle in January, my cycle is only 4 days with the 4th day being barely anything, it says take on day 3-7 so I took all of them even though it was done. 3 days later I started bleeding again for 1 day, that was n February. In march it done the same thing. I only took it that one time. Any opinions would b appreciated
