it sounds like it could be IB since it was soo little! FINgers crossed for you!!!
its so hard to tell anything...if i knew my cycles more i would have a better idea and wouldnt be over analyzing everything but i dont right now
sunday cannot come fast enough
It definitely could have been implatation bleeding, but it is so hard to tell. I would wait until Sunday (although I completely understand if you cave in and test tomorrow). I couldn't tell what your test from this morning said because it was really hard to see. So if you can, try to hold out until Sunday and then use that digital test you have.
