But Alan Gow broke Wycombe hearts when he fired in from six yards with less than 10 minutes left to play.
However, Ainsworth believes there were positives than negatives to take from the game.
"We created so many chances," he said. "We were the only team who were going to score at the end, though it's obviously disappointing to concede.
"In the first half we were the better team by a long way - we deserved that goal even though there was a bit of fortune involved.
"In the second half we started okay then they had a 25-minute spell and made it count. They smelt blood and fair play they got the equaliser.
"I'm not really concerned by the late goals. It would be worse conceding early in games and not getting back into it.
"The lads are down as they know we're on the verge something here.
"It's small margins that win games and taking chances in the box. We were the ones pushing for the winner. How the ball stayed out at the end I'll never know."
