It is very common to experience changes in your menstrual cycle after taking an emergency contraceptive like the i-pill. The bleeding you had on the 12th was likely withdrawal bleeding caused by the pill's hormones. Because these hormones temporarily disrupt your cycle, your next period can be delayed. Please try not to worry. To give you peace of mind, I highly recommend taking a home pregnancy test. If the test is negative, your period should return once your body adjusts. If it is delayed by more than a week, or if you experience any severe pain, please consult a healthcare professional for a quick checkup.

Yes, you can take a blood beta hCG pregnancy test now. Since you took the i-pill (an emergency contraceptive) 10 days ago, a blood test is highly sensitive and can detect pregnancy hormones at this stage, even before your period is due. Please keep in mind that the emergency contraceptive can sometimes alter or delay your menstrual cycle. If the test is negative but your period is delayed by more than a week, it is best to repeat a home pregnancy test or consult your doctor.

While the emergency contraceptive i-pill (levonorgestrel) can cause temporary breast tenderness, a significantly elevated prolactin level of 177 ng/mL and nipple discharge are not typical reactions to it. Since your pregnancy test is negative, these symptoms require a medical evaluation. I highly recommend scheduling an appointment with an endocrinologist or your gynecologist. They will likely suggest repeating the prolactin test, checking your thyroid function, or ordering an MRI of the pituitary gland to find the exact cause, which is often highly treatable.

Taking emergency contraception often disrupts your normal hormonal cycle, which frequently leads to a delayed period and temporary light bleeding or spotting. Because of this, and your negative test result, the probability of pregnancy is very low. To be absolutely certain, I recommend repeating the home pregnancy test in one week, or speaking with your healthcare provider for a blood test if your period still hasn't arrived.

It is very common for emergency contraception to delay your period and cause temporary side effects like nausea, fatigue, and cramping. While your negative pregnancy tests are reassuring, the combination of cramping, back pain, and especially shoulder pain requires prompt medical evaluation. Shoulder pain can sometimes indicate pelvic irritation or other issues that need to be checked right away. Please visit a doctor or urgent care clinic today for a physical exam, and possibly a blood test or ultrasound.

Since you recently stopped Krimson 35, the bleeding you experienced is likely withdrawal bleeding from discontinuing the medication. However, because you have stopped the pill, your fertility can return quickly, meaning there is still a risk of pregnancy from unprotected intercourse. Yes, it is entirely safe to take an emergency contraceptive pill during this bleeding phase to protect yourself. I recommend taking it as soon as possible, ideally within 72 hours of the intercourse, to be most effective.
