I'm 11 or 12dpo test results am I pregnant?

Hello ladies, so I've had no implantation bleeding but has sore nipples although they were pierced 3months ago & still healing, pains in my lower belly every since ovulation, I have been very lightheaded from time to time, and I've been very nauseous after eating but have only threw up once drinking pineapple juice. I took a clear blue digital hpt at like 5am this morning and it read not pregnant but I opened it up and saw a faint line what do u guys think?
All three pics are the same test one is just tweaked
