Help!

Ladies! This is literally the most confusing thing I’ve ever had to deal with in my life...

I’m about 12 DPO, my period was suppose to start yesterday. I’ve had EVERY pregnancy symptom...including a cold, things taste weird...but as you know-most of those are similar to your period...I’m very impatient so I took a test today @ 3 in the afternoon. Said not pregnant...I used clear blue digital but I heard that’s not the best one to use so i went out and bought FR.

I feel like I’m loosing my mind, and idk when to test again?! Advice please!
