I got married in July 2008 and I knew that I needed some BC because I am in nursing school. My Mirena was inserted in March 2008, I didn't want to try BC pills and I HATED The NuvaRing. So my I choose Mirena, It hurt like Hell when they inserted it. But other that that I had not had any problems. In June 2009, I had bad cramping and like a mucousy/bloody discharge., after taking Pain relievers for a few days and then I was fine, But now I have gained so much weight (14lbs in a few months) My belly is perfectly round and my breast have increased size, I am always hungry and craving CRAZY things and feel nausea mainlky at night and I have had increased urination,mood swings, headaches, bloating and Constipation so many prego related symptoms, but my strings are still intact so I am still worried that I am prego and I have been doing a lot of research on this topic and there have been many women in the position that I am in...not to mention if i am what harmful things are happening to the fetus.
