Headaches

Maaaaaan this pregnancy has been good so far(im 22 weeks) no shortening of cervix or placenta problems like my past pregnancies but every day, multiple times a day, i get these horrible headaches.... I spoke to my dr abt it and she says just to drink some soda and itll go away. It does, but it comes right back... Idk what to do. It's hard cuz I'm constantly moving with my 14 month old, my 2 year old, and then my 8 year old.
