Discharge like this

Hi mummies, sorry for the picture. I have discharge like this once in awhile. (Once in 2-3 weeks) Most of the time it’s either clear or white. Should I be worried? Is this considered as an infection? The discharge in the pic has no odor nor am I itching. Anyone experienced this before? TIA! *Its actually light green in the photo but lighting changed it* #firstbaby #1stimemom #pregnancy
