I've been missing my period as while as having it twice a month is there something wrong . I'm 15?

well sometimes having a period that often can be a little much but if it is normal for you i would touch base with a gynocoligist just to get checked out make sure everything is working right and your not having any other problems mabe could be straightening its self out where your gonna mabe get back to having it once a month that the idea get back to regular but go get checked out
