Spotting well after d&c but before first AF

[Anonymous]

I had a d&c 4 weeks ago and my beta went to zero in a week. I bled and spotted for the first week and then it stopped. I have noticed spotting sporadically over the past week that is always faint and pink and usually shows up in the evening when I wipe. I tend to spot a bit before AF, but the spotting is different now than with AF. Has anyone had this type of random spotting after d&c but before first AF? TIA!
