birth control
"I had the Mirena IUD inserted about a month and a half ago. I cramped the day of a little bit and everything was fine. So far I love it, I have only had one period since and have been expecting a second and it hasn't come yet. Unfortunately I am having it removed in a couple of weeks. My husband and I after having sex noticed blood in our areas- and it was from the strings of the Mirena cutting him. This was really painful for him and it is not his first injury during sex since I had it inserted. I would recommend if your partner is rather larger than average that this may not be for you because it has been an issue for us since inserted."
