17.1 here- I have been struggling with significant headaches for over a month. I've been to both the ob and my general practioner more than once- I was very sick in the beginning with a terrible cold  (i work with kids in a school ) it got so bad the midwife actually put me on antibiotics (zpac) a little over a week ago because it wouldn't go away. It did help with my chest cough, congestion , and overal sickness, but I can't get rid of the pressure headaches . It feels like someone is taking both sides of my head in the back and squeezing as hard as they can, all the time .
