My OPK Situation

This is my first month using OPKs. I have been using the Clearblue fertility monitor and wondfos. Over the last couple of days my wondfos have gotten darker and darker. Yesterday was the first time my clearblue fertility monitor said I was high fertility, today is said the same thing. I have to wait for a peak fertility from it. Today my wondfo looks positive. Should I wait for my fertility monitor because it's suppose to be more accurate or BD today just to play it safe.​
