Ivf and ovulating

So I am on day 11 stims today I had ew cm the fertile kind I never really get this but maybe it’s the meds today i went in Monday for blood and ultra sound everything looked good but tues afternoon I had the ew cm I go back tomorrow (wed) for more blood work and ultrasound they are projecting my ER for Friday but my question is could I be ovulating early is the Ew CM a sign of ovulation ??? My doc is closed but I go 1st thing in the morning but can’t help but to worry about this
