Advice needed...

Cheryl • 34 TTC baby #1, married 3 years together 15. Still completely head over heels in love!!❤
Got my smiley face this morning ( clearblue opk) . Didnt notice any cm through out the day but after SO and i BD tonight, (and after I waited like 10 minutes before i got up) i got up to clean up and noticed a large amount of wet stretchy goop like cm. Had a very light almost non existence yellowish/brown tinted. Very stretchy. Is this a good sign?? Is this me ovulating??
