I took femara days 3-7, follistim injections 5-12pregnyl trigger on day 13 and <a href="https://glowing.com/glow-fertility-program">IUI</a> procedure on day 14. The procedure was on a Saturday...I felt terrible. I couldn't function from terrible cramps and bloating. Sunday-Tuesday I was fine. Tuesday night (well Wednesday at 5am) I woke up with a headache. Took Tylenol and went back to bed. Woke up at 730 with a full on migraine! Anyone else have this reaction? Is it just the increase flex of hormones?
