a month and a half ago when I was scheduled to have my period it came, but only for one day and EXTREMELY light. I am usually normal (lasting around 5 days of normal flow). I didn't think much of it, I thought it was maybe a result of a change in diet or lifestyle that month. 2 weeks later, I started bleeding again. This also lasted for one day only and now it is also gone. Can anybody please shed some light on why this is happening? I have been normal my whole life and am at a loss for explanation. Thank you for your help.
