birth control
"I have been using Nexplanon for 12 years with no breaks and I'm about to receive my 5th implant. As you can probably tell from my continued commitment, I find that the pro's of the implant strongly out weigh the con's. Firstly, there are side effects (like most medication). I did receive a little weight gain, I can be a little moody sometimes and my boobs and tummy get very tender once a month, but although I have the hormonal effect of a monthly period I very rarely (once every 3 months) receive very light bleeding/spotting. What's is most important to me is that I haven't never had a child or been pregnant, which is the purpose of the contraception. 
Everyone will react differently. You know what is best for your body."
