birth control
"I got this implant shortly after having my first, and only, child in April 2009.  I was nursing and it was one of the only birth control options that my midwife identified as "safe".  It started off fine.  I didn't have a period for awhile, that could have been attributed to the breastfeeding also.  Within a year though I started worrying about it.  I have gained weight and have a really hard time losing any weight despite calorie counting and lots of cardio at the gym.  Also my period is very sporadic but when it does come it is not unusual for me to bleed moderate to heavy for 10 to 14 days.  During that time I am miserable with back aches, constant cramps and lots of nausea.  I want to get it removed but my midwife assures me it's all normal."
