This is what it looks like when you have a peak or surge, three bars with a little circle represents and "egg" haven't seen EWCM (egg white cervical mucus) or "watery" CM (cervical mucus) to indicate an early + opk.
Once you get your + opk BD (baby dance/have sex) the day of, next day, wait a day then bd again!
Here is the clear blue digital opk. This is simply really easy to use just insert stick every morning and wait till it give you a smiley face. Non fertile days it gives you a 0.
Fingers cross this is our month!!
