Recently took pre-conception blood tests. Results are : AMH-6.7 ng/ml; LH 2.90 mlu/ml; FSH: 5.18 mlu/ml; Prolactin :9.51ng/ml, TSH- 1.15. normal?

Look fine. The doctor who ordered the tests should have informed you that they are normal and that your reproductive hormones seems to be healthy though there is no guarantee that there isn't some other problem which might make it hard to conceive.
