My periods have always been a bit off but the flow is usually consistent and the length is usually 5 days. My last period was late, it was a darker red (basically brown) and only lasted 2 days. I've never had a period like this in my life and I've been having a period for 5 years. I've been crazy moody lately, constipated, dizzy, nauseous, cramping and I've been having horrible headaches. Not sure what's going on!!! I do have cysts but even with them my period has never been like that and I haven't ever felt like this either. Please help!!!
