Hi,
Thanks for query,
As you are not comfortable with pills you should opted IUD.
Copper IUD some times causes this type of
prolonged periods initially but as you have it since Jan 2012 you should remove it to prevent long term complication like
Anemia.
You should try
Hormonal IUD as copper & hormonal IUDs work in different ways. With a copper IUD, a small amount of copper is released into the uterus.
This type of IUD does not affect ovulation or the menstrual cycle. Copper IUDs prevent sperm from being able to go into the egg by immobilizing the sperm on the way to the fallopian tubes.
If an egg does become fertilized,
implantation on the wall of the uterus is prevented because copper changes the lining of the uterus.
With hormonal IUDs, a small amount of progestin or a similar hormone is released into the uterus. These hormones thicken cervical mucus and make it difficult for sperm to enter the
cervix. Hormonal IUDs also slow down the growth of the uterine lining, making it inhospitable for fertilized eggs.
It may change your period.
Thanks.
