Blood Pressure 84/42


My blood pressure is always on the lower end. The last week it's stayed in the 80s/40s range. I'll be 17 weeks tomorrow

Any clue what could help me raise it? Yesterday my OB said all I could do is stay hydrated but I have been. It was 84/42 yesterday at my appointment. I feel like I'm always drained and lightheaded

I've only passed out once
