how long to get a positive

I had went to the doctor on Thursday and they said my urine test was negative 👎🏻👎🏻 but I would've been between 9-10 DPO , not sure if that's still a little too early. I have been having some symptoms of pregnancy like cravings, cheese and raisins, mayo and BBQ sauce, eating more and I've been mood swinging a tenthfold me and SO almost broke up cause I've been so moody- we didn't just were really upset. My period is due tomorrow and my SO insists I not get my hopes up too high but my behavior has raised some eyebrows especially when it comes to eating time. I just don't feel like my period is coming. My boobs hurt way more than normal and they seem a little perkier. I haven't spotted at all today and that unusual. I put in my period as the 5 but I spotted on the 4. So I should've been by tonight. Typical 27 day cycles. I'm so nervous. I wanna go out and buy a test right now. Is that a good idea? Or should I just wait and see if I get AF tomorrow?
