Follicle count on cd3

So I am totally new to this fertility treatment thing and trying to understand it all. I just had my day 3 check and the dr said I had 10 Andral follicles. I thought that sounded nice but when I asked him he said the hope for a minimum of 15 and that this will make it harder to conceive.  So after leaving I looked online and it said more than 8 is within the normal range... ?? I am confused. My AMH was low and he said that is consist with this test. Any feedback/knowledge/experiences would be helpful. Thank you ladies
