Should I take a test? Or is it too soon.

I had some light spotting the 22 and 23 that was either pink and brown. Ive been kinda sad here and there the last two days, as well as having a tiny bit of lower back pain and cramping (don't normally get cramping before my period). I do have PCOS and am taking progesterone.

I don't know, maybe I'm over thinking things here.
