21 years ago, I gave birth to twins, it was my second pregnancy, the first one ending in a miscarriage at 18 weeks. In both pregnancies I had light periods. However, i got sterlised before I was 30 in 1997. My periods since being sterilised have always been heavy, sometimes every two weeks and then every four weeks back to every two weeks. This has carried on until recently, I had my last period 6 weeks ago and two weeks ago I had the normal period spots that appear on my chin and forehead but no period. I know I could be going through the change but I don't have any symptoms of going through the change. Is there a possibility I could be pregnant after all this time? My boobs are sore, but they are always sore at the time of a period, but I do get mega sore boobs when I am pregnant, I have no discharge at all which I normally get when my period is due. Anyone else ever had this happen to them?
