"i was so scared to start this pill because of all the negative reviews, so glad i started anyways!  i had been on the mirena for 5 years and didn&#039;t want another so my dr prescribed me these. first, they were free under my insurance. i have not gained any weight and have had zero side effects! other then making sure to remember to take them, it has been a painless transition. don&#039;t be scared of the bad reviews, what works for some may not work for others! these have been great!"
