Help!!!

Andrea
I'm in my first <a href="https://glowing.com/glow-fertility-program">iui</a> cycle and I'm gonna do my hcg trigger shot tonight. I took femara 5mg days 5-9 and my <a href="https://glowing.com/glow-fertility-program">iui</a> is scheduled for Monday. All of a sudden tonight I've been light headed and dizzy. I know those are side effects of femara but could it hit me this much later? I'm on CD 17! Will that hcg shot make it worse? I have to take that in about 2 hours. Has this happened to anyone else on femara?
