"i was lucky, and was having another procedure done at the same time, so i was under anesthesia when they inserted mine, and i didn&#039;t experience the pain of insertion that some have described. my body is confused though, because i was supposed to start my period the week after, and i had just had a d&amp;c for a biopsy, (which was benign, yay!) so my body tried to have a period, i experienced intense angry mood swings. i saw others had experienced that on mirena. very little bleeding, a little more intense cramping, but advil took care of it. mood swings passed after first couple of days, now i am back to normal. you can feel the string if you search for it in there, but my partner doesn&#039;t notice it during intercourse. i will update in 6mths."
