Bleeding again 4 days after end of period?
I am 26 and usually have very normal and predictable periods. My normal period ended last week and then 3 or 4 days later I started spotting. A day after that it turned into a regular period. The only thoughts I've gotten from others is that it may be stress related, but I am not experiencing abnormal stress so I don't think that could be it. I also do not take birth control. I started back at the gym the day I started spotting, but I've never heard of that causing additional periods (the opposite in fact). What could be causing this? If it's hormonal, is it something I should see a dr. about?
