Pregnancy symptoms no bfp…

I’m 13 dpo and my period is late. But I still have a negative test. I have the same early pregnancy symptoms as last time with morning sickness, bad gas pains, smell sensitivity, extreme fatigue, lots and lots of both egg white and watery discharge which I’ve only ever had during pregnancy. But last time I got a faint positive on the same tests at 7dpo. So now I’m assuming it could possibly have been a chemical and period will start? Is there still a chance of pregnancy?

Edit - let me rephrase - I’m basically asking is there still a chance of pregnancy if I’m testing negative at 13dpo? I’m still not bleeding.
