I'm five days late for my period,I'm still getting lots of discharge, I'm really quick tempered,I've done two pregnancy tests and both have come back negative! I'm very anxious and unsettled within myself I also take depression pills of 10 milligrams could my medication be giving me a negative result? I'm baffled to why I'm not getting my period I've never been late and have a regular 28 day cycle! Am I pregnant again or is it related to stress??
