I am 8-weeks pregnant and my blood pressure (last checked, a couple of days ago) was 130/72. My BP is typically low: 105/68. This is my 3rd pregnancy , I am 29-years old and work out at least 4 days a week for 45 min. My BP also went up with my 2nd pregnancy, but my OB, never paid it too much attention. Why would this be happening and what can I do to help lower my BP?
