"I was on mirena for 3 1/2 yrs, mirena was ok for me in the beginning, however I started realizing I gained a lot of weight I mean ALOT from 120 to 160lbs, I also had no sex drive at all I literally didn't want anything at all with my husband, to the point that it was more of a duty than a pleasant experience for me. I decided to switch birth controls, I overall didn't mind the iud's , I got the paraguard on 02-29-2016 , I noticed spotting for the first 3 days then I was ok. It stopped. One week no bleeding no cramping nothing I was feeling normal again. I started my period on March 14th and is already March 21st and I am still with my period. I think is normal due to me not having a period for 3 1/2 yrs . sex drive coming back so I'm happy :-)"
