21 Days Late.

Hey Ladies! I’m very confused!!! My period has never EVER been this late. The latest I’ve been is about 5 days. And I am currently 21 days late. I have taken about 9 tests including a urine test by my doctor. All negatives. But something just seems off. I have had a little nausea, sore breasts, and an increase in discharge. Is there any chance at all that I could be pregnant still? Even after my test at the doctors. Help!!
