So! Af was due 4 days ago. Nothing happening. No symptoms. Nada. I feel tired abd was starting to worry so did a test. It was negative. I did a boots own one and did it in the afternoon (not 1st pee) it said that was ok on the packet?!? Also, I fear I may have "streamed" above the arrow. How accurate are these things? It said 99% but has anyone else had experience where the result was wrong? I'm not sure what I want the result to be and all sorts is running through my mind (I smoke and will be having a very drunken weekend coming up soon) thanks. Sorry to bore you!
