"finally something that works! i tried 4 different birth controls which caused nothing but problems. i finally switched to mirena at my doctor&#039;s recommendation. insertion wasn&#039;t painful at all. i got the numbing shot and felt absolutely nothing! it was a quick 15 minutes and i was done. i had constant spotting for about 3 weeks which was annoying but the bleeding stopped and now i&#039;m so happy with it! not having to worry about taking something every day is amazing and i&#039;m very happy i switched!"
