What does discharge look like when pregnant?

Ana • Officially PREGNANT With #2!
We are trying to TTC #2. I am officially late 2 days but took HPT yesterday and got BFN. I dont know if I ovulate late. But for about 3 weeks I have had discharge. Sore breasts, no cramps, but unusually really tired. Insight on discharge? Mine is clear, but there is alot of it!
