birth control
"I had the implant placed after having my daughter.  While it was very effective in stopping pregnancy, I always ended up with numerous side effects.  I did not have a period the whole 2 1/2 years I had the implant and now a year after having it removed I've only had two periods.  I starting gaining weight very quickly and have still yet to be able to lose the weight.  I also had mood swings, extreme headaches, and stomach cramps.  This was my experience and I know not everyone has the same issues but I thought I would share my experiences."
