Possible sign of implantation?

CrowLife Cynn
My periods have been pretty off and haven't seen one since January so I was alarmed when I saw signs of spotting this Sunday. Well it stopped within a few hours then Monday it started up again it never got red it stayed a pinkish color never reached my underwear only noticed it once I wiped myself. OK so it stopped again had some cramping on the right side and now it's completely gone. I've never had a light period in my life especially going on and off. So what do you guys think. I need insight!
