Hi there I had what I thought was a period but was far to light for my normal one I had a slight shooting pain in my lower abdomen , I didn't need any pads or anything it was just when I wiped it lasted for about 2-3 days my periods last 5-6 days....... could this be implantation bleeding and when would I be able to test
