I have to agree with the others -- you can't have any symptoms prior to implantation.
When I was previously pregnant, I got implantation bleeding (so I know when I implanted) and an implantation temp dip. I then, for pretty much every single night of my pregnancy, had the symptom you mentioned of having to get up once (or more) per night to pee and I never have to do that normally. I tested at 11 DPO, 3 days post-implantation, and got a positive but I could imagine that maybe I had that one "symptom" at 9 or 10 DPO and would not have gotten a positive then (but I might have if I had tested...it was faint at 11 DPO but not SUUUUPER faint.)
Were you certain of when you ovulated? I can see getting symptoms for about 2 days prior to seeing a BFP but that's about the max. You can't have hcg before you implant.
