Hi, I am 9 wks pregnant. I developed a headache yesterday and usually when I go to bed at night the headache goes away by the morning. Well, I woke up with the headache unfortunately. I felt a little dizzy, so I went and took a blood pressure reading and my blood pressure is at 70/30. I know this is super low. I ate some toast, drank milk, and had a glass of water with my prenatal vitamins. I am feeling slightly better, should I still be concerned and possibly call my md?
