Mucus plug or oil leakage

Sarah • Wife. Momma to a 2 year old. Praying for our rainbow baby.
Ever since I've been taking primrose oil vaginally, I'm scared I won't know when and if I loss my mucus plug cause I have to wear a pad because of the leakage from the pills but the leakage mixed with discharge looks like what some people are sayin is their plug...ugh could my midwife check in an exam?
