birth control
"20 yr. I got Nexplanon Jan 7th about 8 days after my period. I did have the initial arm pain around the implantation site, but I didn't spot right after the implant. I started my period about 28 days later and it was mild at most, for a day. Then, it was more like spotting for about 4ish days, and all i needed was panty liners.  I have been taking aerobics for 10 weeks and I gained weight instead (<8lbs). I have had mild mood swings that I didn't even realize until I read other reviews. I still have strong sex drive. However, I have yet to get my period this month going on 2 weeks late, so I took a pregnancy test and it was neg. Overall, I really like this contraceptive. It's the first one I've tried but so far it has worked pretty well."
