So last month I was six days late, then my period decided to come down. When it was suppose to arrive I was cramping, had sore breast, backaches, and fatigued more than usual. Then it finally arrived, but only lasted two days. Afterwards I had some spotting for a couple of days. All my pregnancy test came back negative. So this month I'm late again, but I'm not cramping or anything like last month. Has this happened to anyone before?
