The hormonal coil

Mirena-Jaydess-1024x680You can also go period-free with the hormonal IUD:
The natural cycle is influenced very little by the hormonal IUD – ovulation continues. The hormonal IUD causes the uterine lining to build up only weakly over the monthly cycle. In most women, this makes their monthly bleed shorter, lighter, and less painful.

After one year of use, a light bleed occurs only for 1-2 days per month. One in five users experience no bleeding after one year of use. This is not a sign of pregnancy, but is due to the direct hormonal action on the uterine lining. Medically speaking, the absence of a monthly period is completely safe and can be compared with the period-free time during lactation.

Menstruation with Hormonal IUD

Within the first 3 to 6 months after placement of the hormonal IUD, the uterine lining stops building up during the cycle. During this phase, light bleeding or even prolonged bleeding may occur. This is medically safe and usually disappears within a few months. Your body simply needs a certain adjustment period. As soon as your uterus adapts to the hormonal IUD, the bleeding becomes lighter and shorter, or stops completely. Very rarely, an unusually heavy and prolonged bleeding may occur after the insertion of a hormonal IUD. If this occurs, you should consult your doctor to clarify the cause. You may want to record a timeline of your periods before and after insertion of the IUD, to help you and your doctor understand the changes in bleeding patterns.

After the first year of use, about one in five women using a hormonal IUD is completely period-free.
The bleeding that occurs with a hormonal IUD in place is normal. It is an effect of the progesterone hormone on the uterine lining, and not a sign of pregnancy. You can take a pregnancy test just to be sure, but it’s not necessary to repeat it. According to the Pearl Index (0.1 to 0.2,, the hormonal IUD is one of the most effective methods of contraception. Only if you experience additional signs of pregnancy, such as nausea and vomiting, should you consult your doctor immediately.
