birth control
"I first got the implant when it was called Implanon from 02/2012-02/2015. That experience was great. Hardly any periods. Did gain weight, but I didn't really care because I have horrible, long, painful periods. Anyway, I got in replaced and my obgyn told me that Nexplanon was the new name and "a little different".  My periods came back and with a vengeance. I have constant weeks of excruciating cramping with maybe 2 day breaks in between. It drives my boyfriend insane, of course. I'm debating on taking it out, but it has kept me from getting pregnant. Literally the ONLY perk."
