Doctor Answers (1) on Menstruation problem
Thank you for your query regarding abnormal uterine bleeding post emergency contraception. I would start by advising a home urinary pregnancy test at the outset.
It is usual to see such menstrual changes after using a hormonal agent, such as that seen in the Levonorgestrel I pill. But the changes associated with medication usually don't last more than 2 cycles. It should also be noted that any variation in the menstrual cycle within 1 week is considered normal.
I would suggest you maintain a regular menstrual diary noting down the details of date of last menstrual period, days of flow, regularity, clots, pain, etc to help monitor your cycles better. Also consider using a regular contraception method after contraceptive counselling.
