Sooo I started my period on Wednesday morning which is the exact date I was due! I have always had consistent cycles fairly light periods no cramps only lasting 3 days. However this month I had stronger than average cramps starting from Monday, my period has been very light but I have only finished this afternoon. Also since finishing I have had a headache, feeling sick and stronger abdominal cramps and pain in the middle of my back where my waist is! This is very unusual for me as my periods have always been the same ever since I first started! Any clues what could be happening?
