Help. I've had diarrhea on and off for the last week. The last two days have been the worst. I started taking the Levest Pill on Sunday after not being on the pill for a few years (used to take microgynon), not sure if this is the cause, seems a coincidence if not. I stopped taking it yesterday so hoping my stomach will settle soon. I haven't been able to keep anything in for the last two days (have only eaten toast) Also fresh blood from period has started again 
. Has anyone had this happen before. Any ideas or help gratefully received. Thank you
