Implantation Bleeding:
Implantation bleeding can be one of the earliest pregnancy symptoms. About 6-12 days after conception, the embryo implants itself into the uterine wall. Some women will experience spotting as well as some cramping.

Other Explanations: Actual menstruation, altered menstruation, changes in birth control pill, infection, or abrasion from intercourse

I had implantation bleeding when I got pregnant. It was 2 weeks after my last period and it was only the size of a dime and for 1 day. It was brownish in color and I did have period like cramps after wards. The cramps felt a little different, but I just though my period was coming early.
