Femara question

Amie

This cycle was my first femara cycle in awhile, and with an increased dosage. I got my pos opk last night but have been in so much pain! Is this normal? I remember headaches from it in previous cycles but not this. I only have 1 ovary, if that matters. My <a href="https://glowing.com/glow-fertility-program">IUI</a> was Friday, was that too soon? Thank you all!
