I need some advice

Madisen
I've been wanting to have a baby since I was 12 I was actually pregnant but miscarried. Now that I'm 18 me and my husband have been trying since last August. I have had 3 miscarriages since we started and I don't know what to do I really want a baby but my body won't support it. I think it has to do with the fact that I was on depo for 3 years. So what do I do.
