Answer

Thanks for clarifying. I understand you'd like to stop taking the pills , but do not like the irregular bleeding that you have. The reasons for irregular periods include thyroid or other hormonal issues, stress, being underweight, being overweight, or having benign masses in your uterus called fibroids or polyps. Given your height and weight, you may be underweight and this is causing your irregular cycles. This would be the likely reason if when you had regular periods, you weighed a little more. I would suggest returning to your physician for blood tests to check your thyroid and other hormones, as well as having an ultrasound to look for problems within your uterus. Once any problems are treated you may find your cycles will return to normal without taking the pill. However, you should definitely use condoms to prevent pregnancy. I hope this helps. Feel free to ask questions, if you have any. Best wishes!
