Multiple periods like that can be caused by many different issue's, such as stress, birth control, life style, or even something like your hormones or thyroid. There are many other serious probs that can also cause this though, so I always suggest being seen by your doc. If your cycle is usually normal every month, I would definitely keep track of how long & how heavy this one is & you should also watch for other symptoms such as fever, chills or anything out of the ordinary for you. It's probably something simple but it should not be ignored. Also most good docs suggest that if a woman experiences symptoms for 2weeks then she needs to seek health care & even though many docs say something like this is normal, in reality it is not normal. Even if it is caused by something simple like stress, it should still be taken seriously. I'm sure you'll be OK but after my experience I always suggest it is better to be safe take care!
