How far along do you think i am?

I had a period at the end of september and should have ovulated around Oct 12. We BD on Oct 11 and i had spotting on the 17th and 18 then nothing. Took a preg test on the 19th, 20th, 24th, 28th, and Nov 3rd

All came back Neg.

We BD on Nov 2nd, and if the spotting on Oct 17 & 18 were actually a abnormal period then i should have ovulated Nov 3rd.

I tested this morning and BFP!!!

So am i 3 weeks (8dpo) going off an Oct 17 period, or 7 weeks going off the sept 24 period? What do you think and why?
