Much has been made of the Scotland international's recent goal drought and his eventual strike against former club Charlton on Saturday - his first goal since a brace at Sheffield United back in November.
But Iwelumo insists he is just keen to play his part for the team and his 14th league goal of the season merely helped Wolves to another three points in their bid to reach the Premier League.
"It was nice to score and it came at an important time for us, but there's a bigger picture and the win was the most important thing because we need points on the board," he told the club's official website.
"I haven't really thought about it being the worst spell of my career, I don't think it has been. With the form I was in before Christmas a dip was always going to come.
"Things were going against me and I was unlucky in front of goal. But it's all in the past, we have seven games to go and we just have to make sure we can get as many points on the board as possible and it's in our own hands."
