This is more than confusing

So I ovulated the 10th of January had sex once.

I thought I started my period as I had all negative pregnancy test and started to bleed on January 24th. My period ended January 27th.

I started taking ovulation test thinking I am not pregnant.

Yesterday feb 1st. I wiped after I peed yesterday which would be 5 days after my period and had brownish spotting that went away. This morning I took a pregnancy test and it was positive. I also took a digital that is positive.

I just am confused on when I conceived I feel like it would’ve been positive after 12 dpo in January it wasn’t. Now I am pregnant. Haven’t ovulated in my second cycle.
