Leaking breast

Sorry if I sound stupid 😬 I'm week 33.6 and while lying on my right side I noticed my right breast has been leaked. It was quite a big patch on my clothes. My breasts have never leaked before (I guess) Is this common or is it a sign that I will be going to labor soon? I'm not mentally prepared yet 😶During my week 32.3's scan doc said everything is fine n no change in EDD at the moment.
