Why can't I conceive?

About 6 years ago I had an blighten ovum and had to have a d&c. I started depo the same day. I have taken myself off birth control about 2 years ago I've been trying to get pregnant ever since. does this mean im infertile? I track my ovulation and have sexual intercourse only to be disappointed when my cycle comes back around. is there something wrong with me?

there is nothing wrong with you my mom did the same thing except it was 4 years and then she ended up have irish twins so it is normal so girls cant right away!!
