You went to your doctor a day after your missed period and the result came out as very weak positive That night you started spotting it was on and off very light Two days already and you are still? Hello there. The test may of been a weak positive because you are in the very early stages of pregnancy or because your having a miscarriage. Its very difficult to say really hun. However you do need to have a pregnancy blood test done again to check your HCG levels. This is the only accurate way of seeing if your pregnant or not. I wish you luck. X
