birth control
"I'm 25 and never had any children. I've been on the pill and had Nexplanon in the past. 
I had it inserted 3 days ago. I'm not going to lie, it is no fun at all. My doctor gave me a shot of what she described as "local Motrin" a half hour before. After it was over my blood pressure dropped and I threw up twice. I generally have bad reactions to all things medical and have been known to vomit for regular blood tests. I had mild cramping the rest of the afternoon, but nothing crazy. The next day I could only barely feel it was there and today I really can't feel it. I bled a little the day of, but that stopped on day 2 as well. I can't speak to how my period will be, but so far so good. Don't be scared! I would totally do it again."
