Hello. Thank you for contacting HCM. I have gone through your question and I understand your concern. After IUD insertion you can have bleeding from days to a couple of weeks depending on how your body is adjusting to it. the bleeding may vary from spotting for weeks to heavy bleeding for a day or two. Although contraceptives such as IUD have the side effect of causing irregular menstrual cycle, abdominal discomfort etc, I would recommend you consult your local gynecologist for detailed clinical evaluation and further management accordingly. Also if these side effects are bothersome for you even if everything appears to be normal you can opt for an alternate method of contraception for future. I hope this answers your question. Please feel free to contact HCM again if you have any concerns. Wishing you good health.
