starting to give up hope 🙁

I am 9 dpo and I keep getting negatives! My af is due on the 2nd and I tried the 6 days sooner 6 times and it keeps coming back negative. I feel like I'm pregnant because I keep having morning sickness and certain sense make me want to vomit. Has anyone gotten negatives at 9 dpo but still ended up with bfp after a few days?
