Implantation Bleeding?

I just wanted to ask if you all think this is

implantation bleeding. My period isn't due for

another week and I'm pretty regular so I don't

think this is an early period. I did experience

mild menstrual-like cramping all yesterday

morning. Then we I urinated around lunch time

yesterday I saw the blood and then the same

amount one more time yesterday evening. So

far today I haven't had any more bleeding. What

do you all think?
