Clear blue Advanced OPK high days

Hey guys!! How many high days do you typically see before seeing your peak day. I have had three high days so far and my glow app says I’m 25% likely to conceive today - with my highest day being tomorrow. I have had three high days so far- CM stretchy heavy and clear egg white- should I have a peak day tomorrow? I can’t remember how accurate this was for my DS. Hoping so badly to have our second little one soon!
