Usually my periods are a bit on the heavy side, always a few days early and I get a dull ache. Last month I had such bad pains on the 4th day of my period I couldn't stand up straight without my knees buckling! It was so bad I thought I was gonna puke and I had aweful chills, too. I took two pain killers and had a nap and they were automatically gone. But, this month, I was supposed to get my period on the 27th but it never came, but I had all pms symptoms. At the moment, I have brown, smelly discharge and a biiiit of blood but the blood or brown discharge hasn't increased at all. Is this normal?
