during pregnancy, you could try that. There also may be something triggering it and if you an find out what that is you could help prevent them. I was getting headaches/migraines before pregnancy but they came more often after and I realized I wasn't drinking enough water or eating as much as I should have been, or even getting enough rest. If it isn't any of those then it could be a hormonal headache from the pregnancy and those I really wouldn't know what to do but take tylenol and to see if that helps.
