Vaginal discharge.

Hi momsies. First of all sorry for the disturbing picture but i really need advice. Im 38w+3 today. Since yesterday i had this milky yellowish discharge. Sometimes it looks like phlegm. And this morning half of my pantiliner was quite full of it. It came out after i got up from squatting down. It does have a bit of smell that wasn't nice to me. Is it infections or mucous discharge?
