Mirena is a very popular birth control option without any kind of side effects. It is a IUD (intrauterine device) which does not require any kind of tubular operation and is believed to be 99% effective. Mirena is famous because it does not have any ill side effects like bleeding, infection, weight gain etc. which are common with other kind of birth control options. However sometimes a woman due to various body symptoms might feel that her pregnancy test result was false negative due to the IUD. Doctors have confirmed that Mirena does not conflict with your pregnancy test but actually is very successful in preventing pregnancy.
Like other birth control pills it does not mask hCG or chorionic gonadotropin hormones. So if in case you are using an IUD and believe that you are pregnant in spite of the fact that your pregnancy test result was negative, it has got nothing to do with Mirena. Either you are not pregnant or you are testing too early. But still you think that you might have conceived than there are high chances that you are testing very early and your urine does not have adequate level of hCG hormones for your kit to be able to detect them.
The chemical composition of IUDs is such that it does not compromise the presence of pregnancy hormones and the pregnancy test result. If you still believe that you are pregnant and are repeatedly receiving negative test result then you might also be testing at the wrong time of the day. Ideally all over the counter pregnancy tests should be used as first thing in the morning and after 2 - 3 days you have missed your periods.
If you're wondering that is it possible to get a false test result while using Mirena then let us assure you that the chances of such occurrence are very rare. There could be some minor side effects of Mirena which might be similar to early signs of pregnancy. Although this birth control does not have any kind of major side effects but still it can make you feel nauseated or have some uneasiness in your breasts. Sometimes it can also make you feel bloated or even you can put some extra weight under the influence of Mirena. The Mirena releases chemicals into your bloodstream and these scenarios are common to occur if the chemicals are not being released regularly and at optimal level.
Theoretically Mirena is designed to last for five years but it can become less effective when it approaches its expiration date. So if in case you need to get your IUD replaced soon they are chances that you might conceive. However if you have conceived than the result would be positive as well and if in case you receive a negative result in spite of the fact that you were expecting otherwise this outcome should not be linked with Mirena.
Can I Get A False Negative Pregnancy Test Due To Mirena?
Yes, factors like testing early, not testing as the first thing in the morning, or not testing in a clean and hygienic environment might be the reason that you have received a false negative. Also if you are under the influence of any kind of medications or have recently suffered with any form of illness then also you are bound to receive a false negative pregnancy test result. So if in case you have the Mirena device implanted but if you still feel that you might be pregnant then you should visit your doctor's lab to get a blood test done. Only a blood test at this point would be able to detect the presence of hCG hormone and the Dr. would also be able to help you with other queries of yours.
