Is this normal?

So recently my body has been producing a lot more discharge than normal and its been kinda milky but watery at the same time? And the the other day I had pinkish orangish discharge my period is 3 days late and I'm 12dpo i tested the day before thanksgiving but it came back negotiable so I don't think I'm pregnant but could it change from a negative to a positive after just a few days?
