22 days late please read

I took a pregnancy test two days before my missed period and it was negative i have not yet taken another (my husband has been out of town and he wants to be there when i take it) i dont feel nauseous all the time just once in a blue moon, my breasts ant sore but i have to pee all the time! Today i had white sticky discharge and i have never really noticed it before. Is this pregnancy sign? What does it mean? I am so ready to take a test tomorrow morning!
