37 weeks, headache & vomiting

So the last 2 weeks have been sheer misery. My doctor hasn’t renewed my zofran prescription because it says it’s due to acid reflux, but I take Nexium every morning. As for the headaches, they are Every. Single. Day. I don’t think preeclampsia because my blood pressure is always prefect, sometimes maybe low. And when brought up to my doctor he says to take Tylenol, which I do almost everyday but really don’t want to but the pain sucks. One day they’ll be in the back, next day they’ll be in the front so I can’t tell if it’s tension or sinuses (taking sinus medicine also)
