How many days before peak do you get EWCM

Jen

Hi ladies. Last month was my first time using OPKs and I got my peak on CD 14. I'm CD 14 this cycle and no peak yet but I did just start getting EWCM today. Last cycle I didn't do a good job of recording cm so I was wondering how many days before your peak do you usually start noticing EWCM? I know it probably varies for everyone, just looking for a ballpark. Thanks in advance!
