Depo has ruined me

I have been on the Depo injection for 5 years since I was 16 and only in my 20's have I started to research what this has done to my body. I haven't had a period for 4 and a half years but I was lead to believe this is normal. My partner and I are ready to conceive now so I never got my injection last month when it was due. Reading all these comments in really worried I will never have a period again and will never be the mother I have always wanted to be. Does anyone have any words of hope or any advice you can give me in this difficult time. Thank you.
