So I've been on the depo shot 3 different times now, at least a year apart (only one shot each time). The first time I loved it, lost my periods, didn't gain weight, it was awesome. The second time I lost my periods but I gained about 10 lbs. Now this time, after having my first child, I haven't gained any weight, but bled for 3 weeks (starting about a month and a half after having her) and wasn't sure if it was because of depo, or just normal postpartum adjustment. I figured that would be it and I'd lose my period again, but it just started today :( I'm just wondering if anyone else has had different side effects each time. I am kind of worried that it's not working correctly and my huge fear is getting pregnant again so soon, although we haven't had sex yet.
