Combined pills suppress ovulation and thicken cervical mucus. When taken daily at a consistent time, typical-use pregnancy rates are low. Missing pills or drug interactions (some antibiotics, anticonvulsants) can reduce efficacy.
Non-contraceptive benefits may include lighter periods, reduced menstrual pain, and acne improvement. Smokers over 35 and people with certain migraine or clotting histories may need alternative methods.
Breakthrough bleeding during the first months is common. Persistent symptoms merit follow-up to rule out infection or incorrect use.
Pills do not protect against STIs; combine with condoms when infection prevention matters.
