Rovers had levelled through Charlie Bennett but Parry said: "It was disappointing because towards the end of the first half we didn't want the referee to blow the whistle because we fancied ourselves for a second goal.
"We had some good chances that we didn't take. In the second half we came out and did not do what we did so much better in the first half.
"We never passed the ball well and when you go a goal down it is difficult to analyse the game after that because you change your game plan and start to push on and leave gaps behind and they are going to get chances. So had that goal not gone in they would not have got those chances."
