My husband and I have been ttc for 4yrs and I had been diagnosed with pcos 3yrs ago. I stopped trying to force anything to happen and haven't taken any meds to ovulate or track it really since its unpredictable. However these past couple days I had symptoms like my period, light cramping and back discomfort, dizziness, nausea, tender breasts, headaches and appetite change I figured I was going to start soon and I had some bleeding when I wiped it was light pink so I assumed it had begun but it was only light pink when I wiped nothing else one day it was just a small spot in a pad. Then the next it was light pink and brown. Yesterday was the 3rd day and today being the 4th I still wore a pad in case and there was a small about the size of a nickel spot on the pad that was brownish red. Could it be implantation or just the start of my period I read implantation ONLY lasts 3days...help ladies?
