Based on the dates you have mentioned, the pregnancy risk is low but not completely zero. Since you took levonorgestrel (i-Pill) within 48 hours, it is expected to significantly reduce the chance of pregnancy.
Brown spotting, irregular bleeding, breast tenderness, and lower abdominal cramps are common side effects of emergency contraception due to the temporary hormonal changes it causes. The bleeding you are experiencing is most likely related to the pill rather than implantation.
Next Steps
However, because you had unprotected intercourse with ejaculation inside, emergency contraception is not 100% effective. Therefore:
* Do a urine
pregnancy test if your next period is delayed by more than 1 week or 21 days after the last unprotected intercourse, whichever is earlier.
* If the lower abdominal pain is severe, one-sided, associated with dizziness/fainting, or the bleeding becomes very heavy (soaking ≥2 pads per hour for 2 consecutive hours), seek immediate medical evaluation to rule out other causes, including an ectopic pregnancy, although this is uncommon.
Health Tips
If the pain is moderate to severe or persists despite the bleeding, I would recommend an examination by a gynecologist and, if indicated, a pelvic ultrasound.
