Can you get pregnant on Mirena? If you are considering this birth control method, this is probably a question you have asked yourself. You want to understand the risks, how this birth control works and its overall efficacy before seeing your doctor. This ensures that you are making the best choice possible for family planning. Mirena has become very popular over the years, but like all things, it is not the best option for all people. Learning the basic information ensures that you are informed about this birth control method.
What is Mirena?
Mirena is a type of intrauterine birth control and is implanted into the female reproductive system. It contains levonorgestrel, a type of hormone. It does not contain estrogen like several other birth control options, making it an option for women with certain cancer risk factors. The hormone released goes primarily into your uterus, leaving only tiny amounts of the hormone in your bloodstream.
How Does Mirena Work?
Doctors and other experts describe three ways in which Mirena works to prevent pregnancy. These include:
- It helps to stop sperm from getting into the uterus by thickening the cervical mucus
- It thins the uterine lining, giving a fertilized egg few places to attack
- It helps to prevent sperm from being able to fertilize and reach an egg
Mirena can remain in place for as long as five years, but you can have it removed sooner if your family plans change. The placement can be done in your doctor’s office.
What is the Success Rate of Mirena?
Mirena is more than 99 percent effective, but there is still a less than one percent chance that you could become pregnant when using this type of birth control. As soon as Mirena is removed, you can start trying to conceive a child. In the last five years, approximately 8 in 1,000 women get pregnant when they are using Mirena. If you think you might be pregnant when you are using this method of birth control, you should consult your doctor right away. You need a pregnancy test from your doctor to confirm whether you are pregnant.
Exploring Ectopic Pregnancy
There is a risk that you can experience an ectopic pregnancy when you take Mirena. This is not a normal pregnancy and it happens when sperm fertilizes an egg like usual, instead of the egg implanting in the uterine lining, it implants elsewhere. In most cases, the fertilized egg implants in a fallopian tube. However, this type of pregnancy can also occur in the ovary, abdominal cavity and uterine neck (also called the cervix).
If an ectopic pregnancy is not promptly treated, there is a risk of considerable bleeding that can lead to death. This type of pregnancy can cause the following symptoms:
- Positive pregnancy test
- Typical signs of pregnancy, such as breast tenderness, nausea and a missed period
- Pelvic pain
- Abdominal pain
- Light vaginal bleeding
- Feeling like you need to have a bowel movement
