Yellow clear discharge = pregnant?

Cd31, af 2 days late, sensitive boobs, af type cramps, feeling so wet. Whenever I check for using pad, it’s just watery discharge. Yesterday there was just one brown spot in the clear white discharge when wiped. Later one spot of pink, then today morning brown spot when wiped, then yellow , now again brown . I have never yellow colored cm ever in my life. What’s going on ? Tested yesterday and today , but bfn. This is my 2nd clomid cycle, with preseed . I’m really hoping for a bfp 😍 What are your thoughts 💭
