I have been diagnosed with multiple uterus fibroids (2 months back). The size is small and my Gynecologist prescribed me with birth control pills. I am regular usually but this time around I missed two doses, however I ensured to take the double dose the next day. The first month of birth control pills did wonders, I had controlled bleeding and periods for 7 days. However, this time around my bleeding has been prolonged for almost 20 days and from the 01st of October I have started having heavy bleeding suddenly. What could be the reason for this?
