BFN at 9DPO still a chance?

AF is suppose to come around May 2nd-3rd and I got inpatient and took a test this morning.. BFN. I had some very light brown/pink spotting the 22nd-24th and then stopped. Now I’m showing a yellow/whitish creamy discharge. I had cramping a couple days during the spotting. My period never comes early or is that light so I don’t think it was AF. I feel like Im having many pregnancy symptoms but getting down that I had a negative this morning. Going to try again in the next couple days. Anyone else take a test at 9DPO and got a BFN and ended up being pregnant?
