OPK Question

Donnaleah • 25, happily married, pregnant with our first little miracle
So I've been taking the Clearblue digital opks. Saturday I got a flashing smiley (high?) and have gotten one every day since then making this morning the 4th one. How many high days do you typically get before the peak day? Or have I missed the peak? I'm new to using these, so not really sure what to expect? Help please!
