birth control
"I received the Nexplanon implant in September 2013, after my gyno was unable to insert the Mirena (I have never had children, so that made it difficult). I have always had irregular periods (usually once every 2 months on average), and my gyno told me that I will probably not get my period very often at all on the Nexplanon. Unfortunately, the opposite has been true. I'm bleeding probably 25/30 days of the month, and it's preceded by a dark brown "goo" that was never present before. In the first few months, I had mood swings (irritability, anger, sadness), but that passed. I am getting it removed soon, but I gave it a 5/10 rating because it did its job -- I have not become pregnant. It did not work perfectly for me, but it may work for you."
