Constant headache

I’m 36 weeks and also going on day 3 of a headache I cannot get rid of. Tylenol has done anything, I’m just feeling generally unwell. I told my doctor this yesterday and she wasn’t very concerned. I’ve had high blood pressure for at least 6 weeks now, my labs are normal, I’m doing a 24 hour urine test, last night my legs started swelling for the first time. But what really concerns me is this headache. I’m so discouraged the way my doctors have been acting about the way I feel I don’t even want to call and ask about the headache because they make me feel crazy, like I’m fine and it’s all in my head. I just want to cry. I feel so lost.
