No. No, Mirena (levonorgestrel) does not release or inhibit the homone HCG which is what pregnancy tests measure. If it is positive, you are pregnant and the Mirena (levonorgestrel) needs to be removed. If it is negative but you think you maybe pregnant, wait a few day and recheck. Obviously you can't wait for a period - those are usually supressed with mirena (levonorgestrel).
No. Not that i've ever heard of.
It is past time for my mirena (levonorgestrel) to be removed and I have been having all the pregnancy symptoms. Can mirena (levonorgestrel) cause false negative for home pregnancy test?
No, unlikely. Today's home pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, vaginal spotting, or medications. A test gives a reliable result 3 weeks after sex (or when conception might have happened) or 1 week after missing a period. If done sooner, a negative result may be due to testing too early, such as less than 2 weeks after conception. Read more...
