No Show Aunt Flow

My cycle is a bit weird, usually, but always within a 2-3 day span. My latest visit from AF was originally due between 1/4 - 1/7. Now, moving into the morning hours of 1/10, still a no show.

My periods are pretty heavy, too. Now I'm just having mild cramping and very light spotting. It changes between a rusty brown and a brighter, pale pink. But it isn't even enough to stain through the TP. Not to mention, it comes and goes sporadically.

I've not tested yet, but plan to. Right now, I just need thoughts from others! I'm on day 35 of my cycle. Thoughts?
