birth control
"So, I've been through three years with Nexplanon, and I am on my second round (I'm roughly six months in at this point). It's been a love/hate relationship.
I stick with it because it's simpler than the pill, and because I cannot take estrogen. But let me forewarn those of you who are thinking about it: it gets rocky sometimes.
My menstrual cycle changed enormously. I'm used to it now, but in the beginning, it was scary. My periods last four weeks on, four weeks off, and they are fairly heavy. They start out light, but get ferocious by the second week before tapering off to nothing. And the cramping....oh, the cramping.
For all that, though, it is reliable, easy, and it works. No pregnancies, no weird side effects, nothing else in my case."
