Test results, confused...

I just turned 40 and had my AMH and FSH tested in October and again last week.

In October AMH was 2.7, now its 1.85.

In October FSH was 4.86, now its 4.69.

Are these decreases in 6 months significant and are the current levels good? They are within reference ranges but I’d like to know in real life what they mean for my chances?

Grateful for any comments xxxx
