45 days PP Brown spotting

Lisette
I am 46 days PP and I stopped bleeding at 10 days PP and now I have been spotting for the past 3 days. I'm not BF and it's Not enough for a pad, just when I wipe. I had implantation bleeding with my last pregnancy so I might take a test in a few days but did anyone else have brown spotting for their first period instead of a normal period? I thought the first period was supposed to be heavy.
