TTC after birth control

Mauii • Mother to Noah & soon to be Zion. Wife to my amazing husband💘 EDD: 2/22/16 👪👶🏽
How long does it take to get pregnant after getting off the depo shot? I only had 2 doses & I been TTC for 4 months now & nothing. Oh & I was on implanon for 6 years before that. I'm afraid I've messed up my body :-(
