birth control
"I took depo for 5 years.  Loved it for the most part.  First starting it was kinda rough. I lightly bleed continuously for 3-5mo for the most part. I had really heavy periods before hand so I didn't think it was that big of a deal. After about a year on it my periods would stop for 2.5 months then start 2 weeks before my shot was due.  MY SIDE EFFECTS: I gained 20 my normal average -30 pounds heaviest being unhealthy on depo. I started when I was 19- stopped @24.  So weight gain is pretty normal so I'm sure it wasn't all depo related.  I also slowly lost my sex drive and it  became nonexistent.  After 5 years I'm getting off because I think I didn't take enough calcium and now my joints started to ache. REMEMBER to take 1500 mg calcium**"
