I Am A 55 Year Old Female. I Have Always

I am a 55 year old female. I have always been pretty healthy. Two years ago had a difficult menopause. Bleed a lot for about a year. Had to lay down on the ground because i thought i would pass out and so on.. Gynecologist put me on birth control to help regulate bleeding. It did help I have been off all medications and stopped bleeding over a year ago. Recently have begun to have dizzy episodes that seem very much the same as they happen. I have had them while driving and pull over while they pass, it has been happening at work, they are becoming more frequent in the last couple days.
