So i had my baby on December 28 2013 and had nexplanon inserted on the 31 of december. Until september 15 2014 my long 9 month period stopped. Its now 3 weeks later and i havent gotten my period but its more like brown/red discharge and spotting. I wasnt sexually active until the 5 month around may but was sexually active last month in september 2014. Im wondering what this could mean. But ive also had alot of fatigue and slight nausea here and there. Could this mean im pregnant
