if you feel you are sitting on the nose of the seat ,yes move it forward a bit, do it a little at a time until it feel right to you and try to keep it level . if it go up to high ,it feel like you being push backward and the handlebars feel to far away . if it to low then you be pushing yourself back onto seat and the wight will be felt in your arms and hands . with your stem you can bring the handlebars closer to you if you need to .
