Depo-Provera Contraceptive and bad breath

i was on the depo shot for 2 1/2 years, and the first 6 months i had daily bleeding and that was with the shot in my arm. after the six months i had moved states and the state i was in only did the buttox shot and as soon as i started that for the next 2 years i didn't have a menstrual cycle. i still had mood swings and a few odd head aches, and ridiculous tooth decay. how ever for 6 months after being off the shot i still did not have a menstrual cycle so i went on Yasmin for a month just to make myself have a cycle. after that month i did have a cycle and went off the Yasmin. after that 1st cycle coming back i had a cycle every other week for about 2 or 3 months. everything finally regulated, and after it had regulated i spent the next 2 years trying to have a baby and it didn't work. I then started monitoring my ovulation, which i apparently no longer have. i monitored my ovulation for about 6 months and it never showed up. i don't know if this was result of the shot or not but i know i had an ovulation before because i had gotten pregnant before i went on it and miscarriage.
