birth control
"I've had the Nexplanon for over 2 years and I absolutely love it.  The only issue I've had with it is my periods are very irregular which is no big deal for me. I get a period for 2 weeks and then I'm period free for about 4 months, then it will return. I have no problem with that. I plan on using this birth control method for 5 more years. I love it."
