I'd suggest getting your thyroid tested (along with any other tests that your doctor might think of) -- my irregular periods were never quite that sporadic, but menstrual problems are one of the symptoms of a wonky thyroid. (And don't let anyone tell you you're "too young" to have thyroid problems. After mine totally gave up the ghost, and I got diagnosed and treated, I realized that I'd been at least borderline hypothyroid since I was a teenager, and I mean early teenager.)

You probably also want to be checked for PCOS, which can sometimes hang out with thyroid issues, or show up on its own with insulin resistance and wonky periods.

Good luck!
