Lampard, who is out of contract this summer, is two goals off the club record of 202 but has not scored since March 17, against West Ham.
He said: "I'm very proud to be on 200. I've only played a few games since that West Ham match and the manager put me in a deeper role.
"Goals never come easy. The most important thing is to be part of a team performance like the other night, when we won at Fulham.
"If I get the chance to play in a few games like that, I think the goals will come.
"Everyone knows my contract is up at the end of the season but I'm just worried about the next few games. I'd be lying if I said I hadn't thought about it but at the minute nothing is happening."
