I just got depo provera 2 days ago and I had a question about it..?

im not sure i have been thinking about taking the pill while im on depo and i have been on depo for 2 years! it can be dangerous and actually all of these people say that you will gain weight when alot of people do but i was 130 pounds when i first started taking depo and im now 90 pounds!!! and if ur on depo you really need to make sure you take a muti vitamin and or calcium pills!!
