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.
