So my period is usually irregular, and last year I did two rounds of the depo proveria. The past 3 months or so my period has seemed to find a steady rhythm of arriving at the 11th or 12th of the last 2/3 months. I've had backpain, constipation, sore boobs all day since October 2nd. My period is die on the 13th my app says. If it doesn't arrive would I be able to get an accurate test result or should I wait longer since I've been mostly irregular, just the last 2/3 months I've actually had it consistent. Pics of my cycles since August. Green color means unprotected sex!
