I got the Nexplanon last year. Things were going great and I had no issues. Lately, though, I've gotten moody and real bad cramps and it feels like my period but is just a lot (and I mean A LOT) of discharge, and this lasts a few weeks then goes away. I'll also randomly have my whole arm go numb that has the rod implanted in it, which has now happened 3 times since Saturday alone. Anyone else experience this? :/ Oh, I'll also add in that I've gained 15 pounds being on it and I can't seem to lose the weight.
