Implantation Bleeding??

Was just wondering what this is exactly??? My cousin has been trying to conceive and has been experiencing light spotting on and off for the last 3 days, took a test and it came up negative, but has been getting AF like cramping for over a week. I told that I wasn't sure about this because I never experienced anything like when I was preggo. Can any ladies give me some info so I can fill her in. Oh and is 5 days late.

Re: Implantation Bleeding??

I am pretty sure implantation bleeding happens at about 10dpo, so it seems like it would be a little late for that. Not sure what else would cause that bleeding. I would probably go to the doc if it continues...then they can do a blood test if they suspect she may be preggo and confirm.
