birth control
"I got the Nexplanon inserted June 30 2014 a week or two after insertion. I had bleeding for 10-15 days, it stopped for about a month and a half and now I'm spotting every time I'm ready to become intimate with my boyfriend or just random times.  I have gained weight and I have felt some nausea.  Yes it's very effective against pregnancy because you are constantly either spotting or bleeding unexpectedly. It's annoying I'm getting it removed very soon. It's nothing fun about bleeding all the time. I appreciate a 4-5 day cycle now."
