Ovulation or a sign of early pregnancy?

Seham • Pregnant with #1 👶🏻 🍼 Due January 2019

Today is CD 19 and I’ve been receiving flashing smileys on the Clearblue OPK since CD 12. We’ve been BD-ing every other day since. I just noticed some pink blood in my CM when I visited the bathroom. Could it be that I’ve finally ovulated or an early sign of pregnancy? Is it worthwhile doing another ovulation test now or wait until tomorrow morning?
