My OPK's have all been negative, I've been testing every day (twice a day - POAS addict!) one had a faint line yesterday but that still means negative apparantly? But my CM (only a little bit so far) is clear and colourless and I'm on cycle day 14. My monthly cycle tracker says I should be OV today and should have been fertile for the last 3 days?? Have BD's everyday for last week and have been using 2 brands of OPK (just in case one was faulty!) so not really understanding whats going on! Any advice greatly appreciated!
