So af is a no show and I have a bfn :( I wasn't going to test until after lunch with the girls, but my friend wante me to test while we were still at my place....but I didn't need to pee lol so I drank a far bit of water to make me go! Is it possible that I got a neg test due to drinking too much water?!?!
