Periods can be funny sometimes. Even if you've been regular you're whole life, a lot of factors can cause your period to come late OR early. If you've recently changed your diet, have been stressed those things could potentially cause your period to go 'out of whack' so to speak. I'd definitely get your hands on a test, and if it comes up negative, I'd speak to your doctor about the strange bleeding. They'd be the ones with ALL of the answers.

I'd also suggest getting on SOME type of birth control, which is another thing you could bring up with your doctor. They'll give you information on all the different kinds, and you and your doctor could pick the one that's right for you. Until then, I'd use condoms. It's the only way to protect yourself from not only pregnancy, but sexually transmitted infections & diseases. So, do something to protect yourself!
