What?!?! You're ex-boyfriend's mom made you get on depo? I don't know why that would happen. But anyway I was on depo for years and I just thought I would throw my two cents in. I did have some strange bleeding during the first shot too. Then I THOUGHT things were getting better because I stopped bleeding all together. But then worse things started happening... consistent morning neck and back aches, depression, migraines, and my hair started falling out in HUGE chunks. Then after being on it more, I started to gain weight... fast. I gained 80 pounds in about 6 months. So finally I talked to my gyno about it and he took me off of it. Then for about 6 months after my last shot, I had the most excruciating cramps I have ever felt in my life. And there was nothing I could do besides lie in bed with a heating pad and see my boyfriend's scared face as he watched me go through the pain. And you think this bleeding is bad? When I got off of it, I bled 5 months straight, having to change my products every hour. My doctor just said it was normal and to take some imbeprofen. Depo is not normal. Also, I was never told that while on Depo to take calcium. After I stopped I researched the shot a lot more and found out that some girls who have not taken calcium while on it can have the bone density of a 65 year old women!
I know this is just my experience, but most of the women I know who have also been on it have their own terrifying stories of it. I would not recommend this birth control to my worst enemy. Here are a few interesting websites I found horrifying after being on depo:
