I'm not exactly sure what it means, but my blood pressure in general is always on the lower side and remains the same throughout my pregnancy. I never had any problems. If this what you are experiencing, ask your doc for advice and if it's a problem.
** lol I meant to say that I was told by my doctor...not my daughter.
I was told by my daughter that pregnant women usually have low blood pressure. I currently have it and I get light headed sometimes. I was told to keep hydated and to drink gaterade.
