Help! Am I pregnant?

[pikapika88]

I am roughly 25 dpo. I don't know for certain because I didn't track ovulation as it's only our first cycle ttc.
AF never really arrived, I had some bleeding on cycle days 30 & 33. On both days it was a small amount of red blood which wiped away and then nothing else. My cycle is usually about 30-32 days. I have had a few symptoms, most notably twinges like minor period pains and I have been quite dizzy and nauseas, throwing up a few times.
I have had BFN on up until about 20 dpo when I got so fed up I stopped testing and assumed I must have either not ovulated or completely got my dates wrong.
But today I was in Tesco and bought another couple if tests and I can see really faint positives on both. But surely it's too late for me to get a BFP? Can you see them or am I losing my mind?

I see them but very faint for 25dpo? Did you confirm ovulation with temping? X

@CalmDown7 I don't really know when I ovulated, I definitely could have ovulated later.
