Discharge

Im just wondering what type of discharge this could be. My expected period is tomorrow. I don’t know if this is a normal discharge for a period about to happen or if I’m possibly pregnant. I don’t want to keep taking pregnancy tests as they can start to get expensive. Ive been having pregnancy symptoms for the last week and half. I never have any symptoms before my period is about to happen except i get more mean. My boobs aren’t swollen but some days they are my sore and today they have some heat when i touch them.
