I have a red slimy gew coming out for about a week now. i thought it was my period. i havent had it since nov. 2014. have taken pregnancy test, (neg.)?

The question: The question is y u haven't had a period since November 2014.Is this something common 4 u?Do u have other medical problems or r u taking a medicine that can cause this?After 5 months u can expect a period to b different than u r accustomed to.If u don't know the reason for the delay, u need to see ur PCP or GYN to look into it.This can be a sign of an illness which can b serious if left untreated.
