I am 30 years old and have never had any children. I had my Mirena inserted on on 7/18 (during my cycle). I know it has only been a week but I'm feeling a little concerned and confused. While having it inserted I was SHOCKED by how painful it was. I, like many other stories I've read, felt like I was going to faint. Sunday I woke up in at 5:30 a.m. in so much pain! It literally hurt so bad that it woke me up. The same thing happened Tuesday. Night time has been a struggle also. I resorted to taking Tylenol PM to knock myself out. I asked my doctor to test me for all STD's to ensure that I would not have a PID, but I'm still apprehensive. I realize I need to give it time... but gosh it sucks being a girl! I'm glad I haven't had any emotional side effects and hope that I never do!
