Ever since coming off the pill about 6 months ago, my cycles have been 28, 24, 24, 24, 25 and 27 days. This month I still have not got my AF and it is day 31. I tested with 'Predictor' on day 28 and it was negative, then today I tested with 'Clearblue' and it came up positive almost straight away! I couldn't believe it! I couldn't believe it so much that I went and bought another test, 'First Response' this time and the result was negative! What is going on? Can anyone advise please? The only symptoms I have are sore boobs, and they've been sore for more than a week now. I also have white / creamy CM.
