I do not know where your origional comment is but I never get headaches and this was my 3rd cycle of Clomid 50mg fr. cd 5-9 and around cd 14 I started getting a bad headache by cd 20 that day I could not even get off my couch and I wanted to cry! My head was pounding!!! I even took one of my DH pain pills and it barely helped. They persisted until about CD 26 off and on but when they were on they were ON!! I really think it is from the hormones. I have heard you can also get pregnancy headaches from the hormones. So hopefully you will end up with a BFP!! Good luck!
oh, sorry - I just saw your other original post. I think I remember headaches being listed as a side effect for the prometrium - I've been on so much **** it's difficult to say what's causing what! I don't know about migraines that severe though. If it persists, you may wanna see your general practitioner about it.
I'm assuming you're on some sort of fertility meds? If so, then YES! Both clomid and follistim gave me headaches. While they didn't seem as bad as yours, everyone reacts differently to the drugs. Some people have no side effects at all, others have every side effect! I hope you feel better.
