Yes, taking the i-pill (levonorgestrel) can indeed cause changes to your menstrual cycle, including heavier bleeding and abdominal pain. Because it delivers a high dose of hormones, these side effects are relatively common as your body adjusts. To help manage the discomfort, you can try using a warm compress or taking mild pain relief. However, if your pain becomes extremely severe, or if you are soaking through more than two pads an hour, please consult a healthcare professional to ensure your safety.
