OPK test negative but egg white cm for 7 days

Okay so my period is due in 3 days....

I started using opk’s a week and a half ago, all negative but I had egg white, sticky, clear, creamy literally a combination of all these types of discharge for at least 7 days even though the tests were still negative.

We are TTC. Would it be possible my body is trying to tell me something?

I’ve also been very bloated but not sure if it’s something I’ve eaten etc.
