Thoughts!? Am I crazy?

I’m 11 DPO…I took a first response digital today and got a BF no - ….we are trying for our third baby. With my first two I had this thing called “lighting crotch” and it was just a sharp pain in my vagina randomly at different times and that’s how I knew I was pregnant even before I tested with those two. I’m having that again!! And also dizzy/light headed feeling. Just feeling super off. BUTTT with my first two I tested positive at 9/10 DPO …so my question is do you think I still have a chance or would the test show by now at 11 DPO ?
