How To Avoid Getting Pregnant After Sex
If you’ve already had unprotected sex and want to avoid getting pregnant, you still have options—but time is critical. Here’s what you can do:
🚨 1. Use Emergency Contraception (ASAP)
💊 Plan B (Levonorgestrel)
- Use within 72 hours (3 days) of unprotected sex.
- Most effective the sooner you take it.
- Available over the counter at pharmacies (no prescription needed in most countries).
- Less effective for people over 165–175 lbs (75–80 kg).
💊 Ella (Ulipristal Acetate)
- Prescription only (in most places).
- Works up to 5 days (120 hours) after sex.
- More effective than Plan B, especially for people with higher body weight.
☠️ Note: These do NOT work if you’re already pregnant. They prevent or delay ovulation.
🧷 2. Get a Copper IUD (Paragard) – Best Option
- Can be inserted by a doctor within 5 days of unprotected sex.
- Over 99% effective at preventing pregnancy.
- Works by creating an environment toxic to sperm.
- Also provides long-term birth control (up to 10+ years if desired).
⚠️ 3. Do NOT Rely on These Myths
- Douching, urinating, or drinking substances (like vinegar or lemon juice) do not prevent pregnancy.
- There is no reliable home remedy—stick to medical options.
✅ What to Do Next
- Track your period and take a pregnancy test 2–3 weeks after unprotected sex.
- See a healthcare provider if:
- You’re unsure which emergency contraception is right
- You vomit within 2 hours of taking Plan B (you may need to take it again)
- You’re late for your next period
Bonus: How to Avoid Pregnancy in the Future
- Use regular birth control: pills, IUD, implant, condoms, shot, patch, or ring.
- Always use condoms to protect against both pregnancy and STIs.
- Consider a long-acting reversible contraceptive (LARC) if you’re looking for hassle-free, very effective protection.
