My feelings are mixed! I like knowing when my fertility is high so to step up the bding but when the high flashing days last for several days it can get stressful. I've used them the last two cycles and flashed for 4 days and then 6 days and this last month it was tough as every time I thought we'd have a night off bding I panicked so it become a total chore. I've got 3 or 4 left so will start using them cd11 or 12 and if I don't get a quick solid smiley I'll go on to using up my normal clearblue digis. There have been a couple of threads so have a read through, some have loved them, I'm on the fence at the moment! Xx
