Very normal. I had it one and off all thru pregnancy. If it's dark yellow or green or has an odor, then I would get checked for infection
I had an infection but already took the meds for it.
I am 24 weeks had the same thing and I have an infection. Just call the dr and explain it
I have had mucus discharge my entire pregnancy. Very normal because of the increase in blood flow and growing uterus. Seems like your fine but If your worried ask your dr
If you are close to delivery then mucus is normal but if not it could be an infection of some kind.
