I've been getting headaches too. My dr said to increase how much water I'm drinking and trying smaller more frequent meals instead of 3 large meals. Seems to be helping some.
I'm 15 weeks well and get them almost every day, I have my husband rub my shoulders and upper neck and they go away very quickly. Tension headaches are very common during pregnancy. A rice sock works as well.
I get them every day, same time, also 15 weeks. I drink a cup of soda and it instantly goes away. Tried Tylenol but it didn't work for me.
It's normal part of being pregnant. Something about more blood flow enlarging capillaries,veins, etc that causes headaches. You can take Tylenol.
