@deiselowen,
You could very well be starting perimenopause, when your cycle can get out of whack. And no, you're not necessary too young for it.
It could also be anal bleeding (not doubting you; just offering a possibility).
But I would call the OB-GYN, just in case. There are some not so nice things which can cause odd bleeding. At least for your own peace of mind, make sure those are ruled out.
