Levonorgestrel
"I got my Mirena a week ago and so far it's been good. The insertion hurt but it took like five to ten minutes.The first two days I felt a little bloated and heavy in the tummy. But from the third day on I never felt a thing again.I was running five miles these days and tummy feels well. The only thing is that I have been spotting lightly since insertion. But I know that it's a common side effect and I just have to be patient.
I think a lot of dissatisfaction stems from the insecurity of not being able to have sex with the constant spotting and your partner potentially losing interest. I felt that way at first anyways, but my boyfriend told me he still loves me and told me to stock up on pads and be patient. I felt loved and relieved."
