Etonogestrel
"I've had this birth control since February 26th. It didn't hurt to get it put in, as long as it's taken care of the right away afterward you should be perfectly fine. Honestly, it was sore just as it should be, but I didn't notice it after it healed. It does ache sometimes now. In February after I got the implant I bled for about a week but it was very light. Since then I have not had a period. I haven't gained weight or lost my hair. I do break out a little more often and I'm very tired more often than I used to be. But I highly recommend it even past these side effects."
