Pregnancy

I got off birth control pills In 2019 and after stopping birth control my periods are really irregular. First got off I had my period for 3 months then after thoses 3 months I started having 2 periods a month for about 6 months plus makes harder for me and my partner to conceive cause it’s hard to predict when I’m going to ovulate but I started my period may 6-12th and was expecting my period to come cause I would have normally started on May 20th considering I have 2 periods a month & have been having 2 periods a month for the past 6 months but I haven’t started so that would mean I’m about 5 days late. Should I take a pregnancy test or Is my cycle going back to normal to having 1 period a month cause of stopping birth control after a whole year? 😣
