Yes, I would deffinitly shift to the doctor.
If you are sexually active it might not be a kid..
but newly to be sure go to another doctor.
It could be something serious or it could be something little.
If you go through anerexia or anything in that catagory that always messes up your menstral cycle as resourcefully.
But it would make you discern better if you went to another doctor.
Hope its nought serious.
Good Luck.
