Wiping old blood after period

JY

So it’s been about to be 2 weeks since my period ended and 3 days ago I started spotting, the first time ever it was red, and it’s brown since then but it’s been 3 days already. I am not even having to use a pantyliner cause it’s only when I wipe and nothing more. I’m going to call my ob tomorrow, but has anyone experienced anything similar?
