birth control
"I have had this implant for 1 year and 2 months now and it's the best type of birth control I have tried yet.  I had a 9 day period a month after getting the implant in and had spotting for about 4 days a few months after that. Since then, I haven't had any type of period or spotting and it is very convenient. My doctor said that women who are on the smaller side tend to work well with this medicine (I'm 5'1 and 100 pounds) and in my case he was right. I haven't experienced any weight gain or skin problems. The only thing I have noticed is my sex drive is lower than it used to be, but that could be due to my anxiety. Not all women have positive experiences with this, but I absolutely think it is work a try."
