do you have blood pressure issues? If not its just good ole hormones!! Take Tylenol.. Drink lots of water... If you have cut out caffeine cold turkey that can also cause terrible headaches!! You can have up to 200 mg of caffeine a day...
Try drinking some ginger tea. I have lemon ginger tea that I add a little bit of honey to that tastes great. It helps me.....
Try to make sure you're eating and drinking enough fluids. I was the same way but I am prone to migraines and that only got worse when I got pregnant. I just tried to get enough rest, eat well, drink enough, and take it easy
Tylenol is all you can take
