You should remove the film now. If those pinholes are still there, they will affect any photos that you've taken on this roll and any future photos.

The best way to check this is to get a flash light and go into a darkened room. Open the camera back and remove the lens, lift the mirror and shine the light through the lens mount. Any pinholes in the shutter will be immediately visible.

I'm using a Crayola fabric marker to fill shutter pinholes. I like this product because it works and the shutter curtain remains very pliable.
