Cluelessly TTC

I was on birth control for a while (maybe 1 1/2 years) then got with my boyfriend . About 3-5 months ago i stopped using bc and my period was coming in pretty regularly but i wasn't actually tracking it in a app or anything . I have no idea when my last period was but i know i was not on my period leading up to halloween and i don't believe ive had my period all month . Those are the days I have been baby making and no positive pregnancy test . I started doing ovulation kits and they are negative as well. Im so confused on what to do next . HEEEELP
