Idk whats going on I've been spotting/light bleeding for 11 days now. I finally thought it was over last night but a little bit ago it started again.... Its vvl almost light discharge and I'm kinda cramping that started yesterday..... Has anyone gone through this and what was the cause???? Last month was the same but it lasted 6 days..... I'm worried!!!!
