Hi!! I'm on day 16 of a 28-29 cycle. I have been using the new clearblue digital tests with dual hormone detectors. I started on day 7 as instructed and got a high fertility (flashing face) on day 12 and have been getting them ever since!! No peak smiley yet! I'm getting worried now as if I don't get it tomorrow I'm worried I will have a very very short luteal stage! Been ttc #2 for 7 months now but this is first month we've used opks! Very frustrated especially as I only have one stick left so may have to go out and buy more!! 
Any help or advice greatly appreciated!!
