I'm glad I saw this topic. I'm on day 15th of my whole 30. I have crohn's disease and fibromyalgia which is why I didn't idea to do this but with in day 2 I got my period and continue to spot ever since. It doesn't seem to be stopping anytime soon. I take birth control that supposed to only give me my period every 3 months and it is 3 months early. What is happening???
