I hope someone could tell me a bit more about this... I have had pcos for the last 3 years and my periods have always been irregular, until 3 months ago I was guaranteed my period on the 8th of every month until now. I was due on the 8th of Feb. and had a active sex , and haven't had a period since Nov.2010. So bought 4 standard pregnancy tests all which were negative. I then started worrying as was still waiting for my period, so went to the hospital for check up URINE TEST IS NEG also,they have told me I now need to wait for another week to wait my period if its come this month. Or is this not a 0 so I must be pregnant? I will go for my check up on Saturday. However I was hoping somebody could tell me a little more about this before I have to wait another week... thanks guys x.. I don't know what happenning to me...
