Hi there, the answer is yes, I was on it for 9 months some years back. I gain 35 pounds, It took a whole year to completely out of my system. It does a number on your bones that's why doctor's don't won't you to stay on it to long because it causes bone loss. Even though you wasn't on it but 3 months. You where probably already predisposed to bone loss before taking it. Try to take calcium vitamins. It would be out of your system soon, as far as the weight loss it can take awhile. My friend was on it also,it took her years to get the weight off. She was on it for 3 months also, hope this help.
I GAINED OVER 100 LBS, 72 IN THE 3 MONTHS AFTER GETTING THE SHOT. FOR SOME REASON I CAN'T LOSE THE WEIGHT AND MY DOC THINKS IT'S CUZ THE **** CAUSED A SEVERE HORMONAL IMBALANCE THAT WON'T ALLOW ME TO LOSE THE EXTRA WEIGHT WITHOUT TREATMENT.
