"i absolutely love nexplanon! i first got the previous version (implanon) about 3 1/2 years ago and i still had a semi-regular period but no really bad side effects. very good at preventing pregnancy, and i love how i can just forget about it for 3 years and have no problems! i got it replaced about 6 months ago, it was a very easy process and the doctor switched me from implanon to nexplanon which is basically the same except for the fact that nexplanon has a  dye to help it show up in imaging. this time around, i basically never get a period...some spotting every once in a while but nothing much. sometimes i have sore breasts but it&#039;s all worth it! very effective and easy. will choose again when i need a replacement in 2 1/2 years!"
