Starting birth control late, such as missing pills or beginning a new pack later than scheduled, can reduce its effectiveness in preventing pregnancy.
Here's a more detailed breakdown:
- Reduced Contraceptive Coverage: Missing one pill may not significantly impact effectiveness. However, missing two or more pills, or starting a new pack more than 48 hours late, significantly diminishes contraceptive protection.
- Ovulation Risk: During the pill-free interval, your ovaries are not suppressed by the hormones in the pill. A delayed start extends this hormone-free period, increasing the risk of ovulation.
- Increased Pregnancy Risk: If ovulation occurs due to a late start, and you have unprotected sex, the risk of pregnancy increases.
Recommendations When Starting Late:
- Use Backup Contraception: If you start your birth control pills late, use a backup method of contraception, such as condoms, for at least seven days. This gives the birth control pills time to regain their effectiveness.
- Consider Emergency Contraception: If you've had unprotected sex after realizing you started late, emergency contraception (EC) might be an option to prevent pregnancy. EC pills are most effective when taken as soon as possible after unprotected sex.
- Consult Your Healthcare Provider: Contact your doctor or gynecologist for personalized advice. They can assess your specific situation, including the type of birth control you are using and how late you were, and provide the most appropriate recommendations.
In summary, starting birth control late can decrease its effectiveness and increase the risk of pregnancy. Taking immediate action, such as using backup contraception and consulting a healthcare provider, is crucial.
