Due date question

no

I have irregular periods. My last period was October 18 lasting 6 days.

My body tried to ovulate on the 6th of November but didnt. And tried again on the 14th and i DID ovulate and I conceived from the 14th Ovulation and got my first positive pregnancy test on the 26th(12dpo) so wouldn't I be only 3 weeks and some days or would they still say I'm closer to 6 weeks(going from last period)?

I'm real confused lol
