amenorrhea
"The Depo Shot is the first birth control I've been on and I would say It's going pretty good. I haven't gained any noticeable weight, just 7 lbs since I started it. I do spot 2 weeks before it's time for my next shot which sucks because that's also the time period where I'm most interested!. Otherwise it's great. I've heard that after a year of use your period stops completely and my one year is coming up next week so I'll let you guys know how that goes."
