Hope for depo victims

I wanted to give hope to those ttc after being on depo. I had my last shot in November 2015 and had never gotten a positive until last week after 20 months ttc. We had tried preseed, semen analysis, blood work, prenatals, geritol liquid; none of it worked for us. We stopped trying so hard and all I did was log when my periods were and when we baby danced. I took the test as a joke because it was my last one, with no pregnancy symptoms I was very shocked! After it being almost 2 years I thought the depo destroyed my fertility(hubby has a child with someone else so we knew he was capable) Don't lose hope just because its been over a year, it can still happen!
