What is the diagnosis for intermenstrual bleeding, nausea, bodyache, fatigue, and gastrointestinal symptoms after taking the ipill (emergency contraceptive) following unprotected sex?

Diagnosis: Emergency Contraceptive-Induced Withdrawal Bleeding with Associated Side Effects

Your symptoms represent expected side effects from the emergency contraceptive pill (iPill/levonorgestrel), specifically withdrawal bleeding combined with common hormonal side effects—this is not a concerning diagnosis and does not require treatment.

Understanding Your Bleeding Pattern

• The brown clots and fresh red blood you're experiencing is withdrawal bleeding caused by the emergency contraceptive, which occurs in approximately 30.9% of women after taking levonorgestrel 1
• This bleeding typically occurs when the iPill is taken in the mid-cycle (which matches your timeline of taking it 1 week after your period ended) 2
• Intermenstrual bleeding after emergency contraception is a normal hormonal response and typically lasts up to 3 days 1
• The timing of your bleeding (approximately 1 week after taking the iPill) is consistent with the expected hormonal disruption that emergency contraceptives cause to your menstrual cycle 2

Your Systemic Symptoms Are Also Expected

• Nausea occurs in 12.4% of women taking levonorgestrel emergency contraception 1
• Body aches, fatigue, and general malaise are recognized systemic side effects of emergency contraceptive pills 1
• These symptoms are mild and self-limiting, requiring no treatment 1

Your Gastrointestinal Symptoms

• The acidity and flatulence you're experiencing are likely related to the nausea from the emergency contraceptive, though this is a less commonly reported side effect
• If you vomited within 24 hours of taking the iPill, the contraceptive effectiveness would not be compromised 3
• However, if vomiting persisted beyond 24 hours, backup contraception would be needed 3

What to Expect Next

• Your next menstrual period may come earlier than expected because emergency contraception taken in the first 3 weeks of the cycle significantly shortens that cycle 2
• The earlier in your cycle you took the pills, the more pronounced this cycle-shortening effect will be 2
• Your next period may also be heavier or longer than usual 2

Critical Pitfall to Avoid

• If you do not have withdrawal bleeding within 3 weeks of taking the emergency contraceptive, you must take a pregnancy test 4
• Emergency contraception is approximately 50-80% effective at preventing pregnancy, primarily by delaying or preventing ovulation if taken at least 2 days before ovulation 5
• If the iPill was taken close to ovulation, it may not have prevented pregnancy 5

No Further Action Needed Unless:

• Bleeding becomes excessively heavy (soaking through a pad per hour for several consecutive hours)
• Severe abdominal pain develops (could indicate ectopic pregnancy if contraception failed)
• You develop fever (could indicate infection, though unrelated to the iPill itself)
• You miss your next expected period entirely 4
