Anyone else experience AF 2x a month?

AF visited 2x in December. I thought, Okay- its just a fluke! My period was late but eventually came in January but now, 2 weeks and 1 day later, I started spotting again. Currently its only old blood light cramps but nothing too uncomfortable... cramp wise... but yesterday and today, my lower back, mostly on my right side has been super painful. Anyone have these symptoms while ovulating? I guess Ill wait and see what comes of it but its kinda annoying. It took a lot out of me in december and im already feeling some moderate fatigue. Anyone have any advice?
