it's all in my head!

I've had a headache for 4 days now! It started in my neck as usual, then became a headache, followed by an overnight, full-blown, all the extras, no sleep at all, migraine! no fun! and I still have it and I am hoping and praying that it goes away soon. I don't know if it's the baby, but I definitely don't want it to last for 5 more weeks!!
