AMH level

We have been TTC for awhile now. Had a failed IUI last month. Before we did it my Dr. discussed with us how my AMH level was at 1.3. I'm 30 years old. She said it wasn't great but not bad. Wondering if anyone else has a "lower" AMH level and still conceived on their own or should I be worried? How much time do I have left? We are taking a break with IUI for the next couple months but still have me on Clomid and we'll try again on our own. TIA!
