hmm, i dont recall this happening before....!?!

Well there's a few things people would need to know before answering this question:

Are you sexually active?
Are you on birth control?
Are you having any pains when using the bathroom?
How long have you had your period for?
Have you always been regular or irregular?

If you're having sex you could be pregnant so take a test in a week.
If you're on birth control spotting is normal especially if you've just started and your body is getting used to having the extra hormones in your system.
If you're having pains when using the bathroom (peeing) then you could have a UTI and should make a doctors appointment to get it checked out.
If you've just started getting your period in the past few months it could take a while to regulate itself and you could just be spotting because it's preparing to come.
If you've always been irregular than this could just be your period being funny and if you've been regular then it could just be an off period.

Usually I only have the bright pink blood when I've torn something during rough intercourse. Maybe you could have a tear from some activity?
