Dear Doctor, I was prescribed a pill Zoely to avoid menstruations, as I have a very low level of iron in my blood. However, I have been taking it for 3 months now and the spotting (which is very abundant, if I may use the term, so that I have to wear a pad almost every day) did not stop. The first month was a mess, then with a second box the bleeding stopped for 2 weeks, and around 15 day of my cycle the bleeding returned, till the end of the box. Then, with a third box it stopped again for 2 weeks, and the same scenario followed. I started a 4th box yesterday, and the bleeding still continues... I have a regular check-up twice a year, and the ultrasound seems to be fine. What is it with me?
