Missed period or just long cycle

Okay so my period is late again .. no surprise to me because my periods have always been irregular but since I am sexual active with my boyfriend I just wanted some advice on should I go get a pregnancy test or wait a little longer to see if my period come. As of right now I’m about 10-12 days late I believe but it’s not to alarming for me because my cycles are usually about 32-40 something days apart.

I been thinking about going to see why my cycles are so long but I feel like there just going to say what I already know that since I been on birth control it might take some time for your body to become regular again but my cycles have always been irregular since I first started getting them and I been off birth control for a year now .

🙄😩 like why I can’t just have a normal period so I won’t be stressed ever month
