Has anyone had trouble conceiving after years on birth control?

I was on the Depo Provera shot from 15-17 and then on the Nexplanon until I was 18. I am turning 20 on the 18th, we have been actively trying for over a year with no luck. I take prenatals, changed my diet/exercise, take maca root & use ovulation tests. I feel like my birth control had a big impact on why I'm not pregnant yet.
