Please answer! Do I still have hope?

Brandi-lea • Khaleesi-May Dizney Van Vliet - my precious daughter born on 23.6.15 👶🏼🌸
I thought I ovulated on cycle day 16 but I really ovulated on cd 17. Meaning I was due for AF today (14dpo) she hasn't arrived which is great! 
​I've been testing for a few days with a few different brands of tests and a few different Batches of the same tests and got a faint line on 15/17 of them. I tested today with a clear blue digital with weeks estimator and got a bfn
​Do I still have a chance? Symptoms galore this month which is odd as I have never experienced symptoms like this!
​Constipation , heartburn, increased acne, no appetite, nauseous but no sickness, extremely tender breasts, spots on my nipples (lots of them too) , a blue ring around my nipples and also nipples are a lot darker and bigger! Veins popping out of my breasts which I've never had, cramping and twinges in uturus as well as left and right pelvic pain! Fatigue and very vivid dreams At night for the past week!  
​Could I still have a chance at getting a  bfp even with a bfn at 14dpo?? Please help ladies? Want to know if I should just let it go and wait for AF now? 
​Here is my chart
