Hi  i had an IUD then started Avianne in early June. My periods are usually 5 days.  I had heavy bleeding for 4 days, then nothing for 2 days, then heavy bleeding with clots and change of tampon every hour for four more days. I have no pain.  Could this possibly be the Avianne? What are some other possibilities ?Thanks you
HelloThanks for your query. It would not be the Arianne. Birth control would cause mild spotting / bleeding.The IUD is generally responsible for such heavy bleeding, or if you have had it removed, hormone with Chat Doctor. Being on blood thinners, thyroid hormone imbalance, anemia, polycystic ovaries, endometrial hyperplasia - all are some other reasons. Have a thorough gynecological evaluation to pinpoint the cause. Take care.
