TMI.. discharge on underwear

I’ve been having watery discharge for about 4 days now and I am currently 2 days late on period. This is the first time this has happened to me to last this long. Is this normal or possibly a sign of pregnancy? No itching, no smells, or anything unusual. My husband and I have been ttc so keeping my fingers crossed.

*the lighting makes it look yellowish but in person it’s milky white color*
