NEED ADVICE! Had a miscarriage, regret taking the depo shot...

This is going to be a long one...

Im 19 and my bf is 20 and on August 2017 we found out I was pregnant.. On December 24 2017 I had a miscarriage. On January 16 2018 I decided to get on birth control which I didn't want to but I thought it be best for us since we're so young... and I regret it.. I was on the Depo shot. I started started gaining weight, lost interest in sex, I didn't like not having a period and found out that after that shot it could take to a year or 2 for my period to come back and for me to become fertile and to ovulate again. So my next shot was in April and I decided not to take it.

It's August 2018 now and I just would like to know if this has happened to any one else, how can I get my period back or what should I do? I was so happy that i was pregnant, now I'm worried if I won't be able to again..

Anything or any advice is good! Thanks💙
