Andy Reid gave Forest the lead with a brilliant free-kick on six minutes that Scott Carson could not keep out.
Jordi Gomez scored what proved to be the winner on the half-hour mark after Fortune's shot had been tipped on to the bar by Karl Darlow.
"We weren't ourselves in the first half and we deserved to be behind," said Davies.
"We did better in the second half and I thought we deserved something in the end.
"We were much more like yourselves in the second half, but we needed a break and we never got it.
"I'm delighted with where we are so far and the position we find ourselves in going into the break.
"We'll look forward to a bit of a break now, because it's a long season ahead."
