A few days ago i had this pain in my heart . It felt like someone was stabbing it when i laughed/cried/sneezed or took deep breaths and sometimes it felt like it was doing flips. It hurt all day and a bit the next day then was fine. What was up with my heart? Oh and also, i dont know if it has anything to do with that but on that day, my normally light period was really heavy and i was wondering if it had anything to do with my heart and blood?
