Just wondering if anyone can tell me if these values are considered low, and is it dangerous? This is what my bp was when i was preg at each ob appt;

118/66 week 9
120/66 week 14
110/60 week 18
110/48 week 23
108/46 week 35
108/80 week 38

At week 30 I also got a sudden bout (sp) of alot of white flickering in my eyes, then blurring, and dizzyness. It lasted for about 20mins then went away and didnt get it again. Could this be related to my bp?
