People taking the minipill should not experience headaches or migraines from missed pills related to estrogen withdrawal, since the minipill contains no estrogen.
Notes on verification
Confirmed by multiple independent medical sources (Mayo Clinic, Cleveland Clinic, Bedsider) that the minipill contains no estrogen, and by clinical literature (ICHD-3 criteria, AJOG systematic review) establishing estrogen-withdrawal as the mechanism behind pill-related headaches. The logical inference connecting these two facts is sound and unopposed by contrary evidence.
