I have taken 3 of 5 doses of Letrozole and have been responding well. Except I started spotting, and not just a little.
I'm planning on calling the clinic first thing tomorrow when they open, but just was curious if anyone else has had a side effect like this.

Diagnosed with PCOS March '10 - Started 1000mg of Metformin
After 3 unsuccessful Clomid cycles, FSH+Ovidril+IUI+Progesterone=BFP!

Time to make Emilie a big sister!
May '16 2.0: Letrozole+FSH+Menopur+Ovidril+IUI+Progesterone=BFP! first beta-45.44, second beta-148
