Common Migraine

Is it common to have headaches when you're 12 weeks?
I have 12 weeks along, and recently I have been sick in front of the border on migraine. He had headaches before getting pregnant, but are most common, 1-3 per week. Anyone else experience during pregnancy? Each time I go to my DR BP is normal range, even at the bottom.
I started getting moderate to severe headaches around week 14. I called my doctor. and explained to me what is normal due to changing hormones. Now, I take a drug for migraine if I am a bad person who turns on (Isometh) and is safe during pregnancy. I am 20 weeks now and still get PG. ) -: Good luck!
