implantation bleeding

How many of you ladies have experienced implantation bleeding? Im 17 days late for my period and feeling some cramping, should i be worried?

Hi. I don't know about many others, but I don't recall implantation bleeding, pain, or anything like that with EITHER of my two children, but that's just me. I didn't have any morning sickness either, so...???  However, I DID have menstrual-like cramps just before I found out I was Pg BOTH times, with just a hint of nausea in the evenings a few times with both, but other than that I never experienced any "implantation bleeding", pain or anything along those lines... Hope this helps... Good Luck! =)
