Hello! Please help me to understand what is happening. I'm in so much pain right now, I'm on my period cycle day 3, normally my period is between 6-7 days, first day spotting, heavy and medium flow second to third day and and then it's light and spotting. Today i'm still not bleeding "properly" it feels like my period is stuck.. I've got agonizing cramps that are painwise like labour, yet minimal bleeding. I've never had this happen before, I'm 100% sure I'm on my period. I tend to bleed quite heavily during my period so this is very unusual. I can't be pregnant as we always use protection and didn't have any slip ups and period came on exactly as normal. I do have endo and PCOS could this be causing this? What can I do? Please help! ;/
