I gained weight on it - about 20 lbs. AND I got pregnant!! My depo-baby is now 3 and doing quite well in preschool thank you!

Of course I also have a Ortho Trycyclen Baby who is 2 and runs me ragged! He's pictured in my avatar.

So now my tubes are tied, but that's my own fertile myrtle story. I would definitely check into the IUD, I heard there is a new one out that is supposed to be really effective and safe. Any hormonal birth control can screw with your insulin and therefore your weight. Good Luck!
