Log the pill (daily adherence + streak), hormonal IUD, copper IUD, and implant in one accordion. Insertion, strings-check, and removal events are recorded with dates. Predictions, regularity, PMDD scoring, and Pattern Mirror are method-aware: cycles on hormonal contraception are excluded from your natural-cycle baseline so switching methods doesn't pollute your stats. Hormonal IUDs keep fertility predictions visible (per Mirena/Skyla DailyMed: ovulation usually continues); the pill and implant suppress them.
