Ovary Pain While On Femara

My doctor has me on 7.5 mg of Femara from days 3-7. Since the second day of taking it, I have been having very bad ovary pain. I know they are just developing follicles, but it's very annoying and hurts. I don't remember this happening with Clomid or Femara before, so this is kind of weird. I'm going for my cycle day 10 monitoring appointment tomorrow. Hopefully, they'll have a reason as to why I'm experiencing so much pain.
