Since you had unprotected sex near her ovulation day, there is a possibility of pregnancy. While the emergency contraceptive pill (i-pill) taken 1.5 months ago is unlikely to affect this current cycle, a two-day delay can also be caused by stress, PMS, or natural variations. To find peace of mind, I gently suggest she takes a home pregnancy test, which is highly accurate now that her period is late.

The bleeding and lower abdominal pain you are experiencing on day 15 are very common and normal side effects of the emergency contraception you took on day 9. Levonorgestrel often causes temporary cycle disruptions, spotting, and mild cramping. Additionally, the risk of pregnancy from non-penetrative genital contact is extremely low, as sperm must enter the vagina for conception to occur. Your body is just responding to the hormones. If the pain becomes severe or the bleeding is very heavy, please consult a healthcare professional.

Because this emergency contraceptive delivers a temporary dose of hormones to delay ovulation, it frequently alters your regular menstrual cycle for that month. This is not a sign of a serious medical problem. However, to give you complete peace of mind, I highly recommend taking a home pregnancy test if your period is more than a week late, or about three weeks after taking the pill.

Since you have already taken this emergency contraceptive, no further oral medications are needed. If you want additional protection, a healthcare provider can insert a copper intrauterine device (IUD) within 5 days of the encounter. For now, try not to worry. Your next period might be slightly early or late due to the hormone. If your period is delayed by more than a week, taking a home pregnancy test will help put your mind at ease. Please consult a doctor for personalized support.

The withdrawal method carries a risk of pregnancy, and day 13 of your cycle is within your peak fertile window. Regarding safety, using emergency contraceptive pills (such as levonorgestrel or ulipristal acetate) in consecutive months is medically safe and will not harm your future fertility. However, frequent use can temporarily disrupt your menstrual cycle, causing irregular bleeding or delays, and is less effective than regular birth control. Please rest assured you are safe, but I encourage discussing a highly reliable, ongoing contraceptive plan with your doctor for peace of mind.

Emergency contraceptive pills contain hormones that work by temporarily shifting your natural cycle. Because of this, experiencing spotting, unexpected vaginal bleeding, or having your period arrive early is quite normal. Your body is just adjusting to the medication. Typically, your cycle should return to its regular pattern by next month. However, if the bleeding becomes very heavy, is accompanied by severe pain, or if you want peace of mind, please take a pregnancy test in a few weeks or consult a healthcare provider.
