Girls during screening found my high risk of preeclampsia. I usually have low blood pressure 100/70, 90/70. But for two days already 120/80, 125/80, terrible headache. The doctor didn't prescribe anything, just told me to measure and observe. Only to her will I go. How long should it rise to drink ?? Also, did anyone take hawthorn (herbal)? It lowers blood pressure, heard.
