could it have anything with using the tampon for that long, because, i just started my period day before yesteday eve. so then that day was my first heavy day. then it just quit when i took the tampon out.
Tampons shouldn't have an effect. It is healther though if you do not use one for that long. Not because of blood flow but because it could cause an infection.
Its a rare phenomenon, but it does happen. My cousin suffered from it.
(you'll find what I'm referring to in the insert inside the tampon package)
Periods are (in part) because your endometrial lining sheds each cycle. It gets thicker during your cycle, then sheds at your period if you are not pregnant. So, using a tampon won't affect how much tissue is shed. Like I said, some cycles are just funky. Don't worry too much--unless pregnancy could be a factor.
