depends on how early. could indicate a possible miscarriage but it sounds like you had to have been pregnant through last months period if that's the case.
Hi I got that It called Implantation bleeding which is a pregnancy sign but got my period 2 weeks after you don't always mean your pregnant. Pink blood is fresh it isn't old blood. Go to the doctors...
you could be stressed, pregnant, or you could have started early because someone you've been around a lot lately started 2 weeks earlier than you and that caused you to start around the same time.
