I'm not sure if my condition is related to my cycle but i always have low blood pressure symptoms after i had my menstruation. My period just finished and i started to have dizziness every time i make sudden movement. Whenever i stand up, everything seems to be blurry and i feel like i'm going to fall. Usually this lasted three to four days. After that everything came back to normal. This condition started few months ago. So i was just wondering if it's related to my menstruation at all.
