12 dpo and spotting 3 days before period

Latasha

I’ve been spotting only when I wipe . The 1st two days were really really light and rhe3rd Dave became a little bit darker but only when I wipe . Only enough to wear a liner... there is no clots or clumps in blood...I have experienced light cramping and back ache n tender hurting nipples. Usually I just get my period the next day or the same day when spotting....any suggestions or same stories
