I Experienced Brownish/pinkish Spotting 4 Days Before My Period Was Due Followed By 2 Days Of Bright Red Bleeding ( Not Heavy ). What Could Be The Cause Of This? Could I Be Pregnant?

Sounds like you got an early period.

The brown blood is usually old blood, it could have been something you didn't sluff off in your last period. It does sound like an early period to me too... anypain?
