Bleeding After Morning-After Pill: What's Normal and When to Worry

Bleeding or spotting after emergency contraception (levonorgestrel or ulipristal) is common and usually normal.

Expected Patterns

• Period may come earlier, later, heavier, or lighter.
• Spotting between periods.
• Cycle typically normalizes within 1–2 months.

Why It Happens

High-dose progestin disrupts endometrial stability and hormonal feedback, triggering withdrawal bleeding or altering ovulation timing.

When to See a Doctor

• Heavy bleeding (soaking pad/hour >2 hrs)
• Severe abdominal pain (rule out ectopic)
• No period within 3–4 weeks (take pregnancy test)
• Persistent irregular bleeding >3 months

Key Reminders

• Not 100% effective—take ASAP after unprotected sex (best within 72h for levonorgestrel, 120h for ulipristal).
• Not for regular contraception.
• Side effects: nausea, headache, breast tenderness, fatigue.

Follow up with a provider for ongoing contraception and STI screening.
