I absolutely hated the mirena. It hurt so much. Being intimate with my husband after I had it implanted was almost impossible. If he went to deep he would hit the wires hurting him and I. It killed my sex drive and I gained forty pounds with it. I had it removed after a year and finally started feeling like myself again.
I'm not at all a fan of hormones, so Mirena isn't an option in my opinion. I had a very good experience with Paragard prior to my first child and I'm planning on getting it after this baby is here. I had no issues with it and thought it was really simple and easy.
