spotting ,cramps, and BFN

a couple days after my missed period I took a test, neg. , but I've had light spotting like brown stuff for about a week now , not even enough for a pad but I'm cramping alot everyday all in my back and I feel bloated. some history haven't had a period in almost two years and finally had a regular period last month. we've been ttc for almost a year now should I be hopeful or is it my body trying to get itself back on track?

[ I've been back and forth to the doctor to see why my period has been absent hormones are normal, and tested neg for pcos.]
