I'm not so sure AF arrived and if she did she is weird.

I thought she came 3 days ago because i hade very little brown spotting so i thought that was the start of it....but now 3 days later the same thing.....very very little brown spotting....like a drop. Does this usually happen the first time you get AF after a D&C? Do I even consider this AF? My D&C was 5 weeks ago. Ehhhh I hate this!
