First period (TMI?)

Anyone still exclusively breastfeeding and no period? My baby is about to be one in a week. I thought I had gotten my period but now I’m second guessing it. I didn’t have actual bleeding (super super light) and no cramping. The color was a tinge of bright red for one day but the amount was something you’d get from a small cut. The days following were brownish. Along with some low back pain and a headache.
