Hi,
I am 21 and I have recently has some changes to my period, nothing painful and I don't think about the changes until I get I get my period again the next month

I have always used tampons it is just my preference and the last while It only get soiled on the one side of the tampon. Its like the left side is not functioning. Is this serious... I sometimes get the brown blood at the end of my cycle and my period only usually last 5 or so days.

Any help would be appreciated
Thanks

It's really no big deal, it doesn't mean that you are flowing from one side or the other as you only have one uterus... it basically just means that the flow is flowing down the right side of your vaginal canal.

Nothing to worry about.
