Milky white discharge

I’ve had this milky white discharge for 6 days now and af is suppose to come in 4 days I’ve never had this discharge before and it’s so much of it I’ll go to the bathroom thinking that af is here and instead it’s a puddle of this discharge and it doesn’t smell I’m not itchy down there nothing burns or bothers me I did have sex unprotected on one of my fertile days but I’ve never been pregnant before so I don’t really know if that could be a symptom of early pregnancy I know everyone’s different and pregnancy symptoms can mimic period symptoms but I’ve never had this discharge before
