"this birth control is a nightmare. i&#039;ve had it for about 2 years now. when i first had it implanted i didn&#039;t have a period for about 3 months. after that, i&#039;ve had my period for the last year and a half. it only stops for maybe a few days every 1-2 months. after my period stops for a few days i have very bad cramps when it comes back. i also developed very, very bad brain fog after getting the implant. it makes me light-headed and dizzy...so bad that half the time i can&#039;t even drive my car! it makes it very difficult to focus. it has also given me moderate to severe acne. i take very good care of my skin, but the acne will not go away. sex is also extremely painful, i have breast tenderness, and at one point it gave me vaginitis."
