Felt like I started my period

Ok.. so I don't normally have discharge that is so heavy. I am day 4 of my fertile window. We had sex twice within the 1st 2 days of my window. He went on field yesterday. (Army) So i havent had sex since..Today I felt like I started my period, very wet down below. (I'm not due for AF for another 3 weeks) but when I checked it was thick in my panties. It was thick white creamy like. Not the egg like goo, that is normal at ovulation. I don't normally get that wet in my panties. Not my normal. No smell. What is it?
