Af has always been regular, if I'm late I'm normally 2-4 days late max I'm currently around 13 days late, I've noticed some increase in white order less discharge, slight cramping not like menstral cramping just  slightly lighter, also notice my boobs feeling quite sore especially around the sides of them sometimes it feels like someone just punched me in the boob.. I've taken home pregnancy test and it came back negative... going to see my doctor tomorrow! Any thoughts on what may be going on?? I'm kind of confused and puzzled at the moment...
