birth control
"I have had the Implanon for almost 2 yrs now and I wish I would have never had to switch from the patch. When I was on the patch I had NO problems, no weight gain, VERY regular periods, no acne. I had to switch to Implanon because I can't use a birth control with estrogen. Since starting Implanon my periods are very irregular. In fact, I bled for the first year and a half with maybe 2 wks of a break TOTAL. The only good thing I can say about it is, I haven't gotten pregnant. My skin also changed, I have never had a problem with acne and now my forehead is oily and constantly breaks out, as does my back.  I have also gained a total of 10lbs which I can't say it totally caused by Implanon. I plan on taking my Implanon out soon and finding another method."
