I am 21 years old, without any children and my GYN suggested to me to try Mirena because I've been having abnormal bleeding for awhile now. I've been on Seasonale for almost a year now and prior to changing to this pill I had lost almost 18lbs and since then I have gained it back. I am afraid this Mirena will be extremely painful for me as I have not had children, and as I am sexually active in a steady relationship I am afraid that it will change my sex drive. Will my partner feel the strings coming out of my cervix? Will sex be painful at all with Mirena? Please help!!
