Hi, I just had a baby a week ago. I was put on magnesium because I had high blood pressure. I'm now on medication to control my blood pressure. I don't know if this has anything to do with it but, when I don't take my pill or I'm late. I feel my heart beat rising but its not actually rising. I feel shaky which I think is out of nervousness, hotness, slight headache And a weird heart burn feeling. Any idea on who at that is?
