Is there still hope?

I have been experiencing different pregnancy symptoms for 2 weeks now (bloating, nipple sensitivity, abdominal cramping, headaches). I’ve taken hpt because I’ve heard and seen people getting faint lines before two week mark but they have all been BFN’s. AF also hasn’t made an appearance yet either. Tomorrow marks 14 DPO and I plan to take a test just to be sure. I am honestly expecting a BFN still. If it’s not pregnancy or AF then what the heck are these symptoms alluding to?!
