Could I be pregnant?

Okay guys! So I'm trying to conceive. My expected af is in 6 days. My cervix never dropped after ovulation remained high, closed, and now extra soft. Two days ago my breast got sensitive (mainly the left, left also has a milky? Substance if squeezed). I've been nauseous and dizzy but that's typical. And I've had creamy discharge. And acne so bad. Got a BFN two days ago. Any thoughts.
