Light green discharge

So im noticing every now and again when i wipe there is some light green discharge. Not a bunch just a couple spots. Most of the time its white or like a milky texture.

Just asking because i just recently moved and haven't seen the doctor since i was 21 weeks. Waiting for my insurance to switch.

Currently 27 tempted to go to the ER but i dont know what to say if they ask me wjats wrong because i feel fine and i dont want to lie to be checked out.
