birth control
"I am 23 years old. I got the Nexplanon right after my son was born. The 2 first months I bled like usual than I began getting 2 periods per month. That lasted about four months. I did see lots of blood clots and dark brown blood for several days when period was ending. I've been on this contraceptive for over a year and 3 months and the bleeding still is no joke. Besides the long unpredictable periods I had no other side effects."
