I had the mirena (levonorgestrel) iud put in about 4 months ago and i have been having a lot of pregnancy symptoms, is that normal?!?!

Depends on symptoms: Some common symptoms with the Mirena (levonorgestrel) iud are irregular bleeding and discomfort from ovulation. You should check a pregnancy test to be on the safe side.

Maybe: It is not uncommon when a woman first has a Mirena (levonorgestrel) put in to experience symptoms such as fatigue, nausea and headaches. This usually goes away with time. Those, coupled with the absence of a period can take a little getting used to. It doesn't hurt to check a home pregnancy test just to be sure and for peace of mind.
