So I am two days late for my period. I have had faint cramping. More like a random pulsing pain in my pelvic region. Almost like pms cramping but not as much. Only a day or so ago. Also, an awful headache that has last more than 12 hours and I have had heavy thick creamy discharge. I am not ever late for my period. I almost feel like I don't see any signs of starting like I usually do. My back had that faint burning pain a few days ago which is one of my signs I am starting my period but haven't yet. Has this ever happened to anyone or does anyone have an idea of what it may be?
