AMH and AFC

Good Morning. I am 31 and have a hormonal IUD. I had fertility testing done and my AMH came back as 0.18 however my AFC was 16. Estrogen 88 and FSH 2.35. I don’t know where I was in my cycle when I gov the testing done since the IUD stopped my periods. Prior to insertion, my periods would come every 19-21 days. Which is more indicative of fertility, my AMH or AFC? I don’t plan of having a baby for another 1-2 years. Thank you.
