The 26-year-old has played just 101 minutes out of a possible 360 under new Royals boss Nigel Adkins.
"I'm like every footballer. I want to start, I want to play games and at this moment I'm not getting anything," Le Fondre told BBC Radio Berkshire.
"If it continues I do not know what will happen."
The Royals top scorer this season admitted to being baffled as to why Adkins did not turn to him with the club trailing Norwich 2-1 on Saturday.
"We needed goals and that is what I bring to the table," he said.
"I want to play every game, I want to start games but most importantly I want to come on the pitch and affect things and make an impact.
"It is disappointing from my point of view that when we are pressing so hard I can't come on the pitch and influence it.
"I have no idea what happens with me. It's in the club's hands. I've had a half-decent season by my standards."
