Low Amh , Need To Know How To Conceive Naturally

Hi all,,

I am 28 yrs old and I got married before 3 years and trying for a baby since then.
Recently came to know that my AMH is low (0.67).Tried 2 IUI's but nothing helped.
Can someone tell me
1.what are the supplements I can take
2. What are the precautions to be taken after ovulation
I have prayed all the god and even visited Navaneethakrishnan temple and garbarakshikambigai temple (but no one is showing consideration on me and making me cry everyday).

I am not able to feel happiness around me and am longing for a kid
Leading a very mechanical life. Someone please help me if you have conceived naturally with low AMH.
