HELP! please give an opinion or some advice!! I really need help!

I am currently 10 days late from starting my period but every time I test I get a BFN. I have had several symptoms like cramping, Nausea, cold symptoms, indigestion, migraines, and back aches... is there still a possibility that I could get a BFP or should I just chill and keep trying?! So terrible at the waiting game 😂
