Apart from the good advice from other posters I would like to stress that this is a trimming problem which you should discuss with your instructor.
With low hours its perfectly normal to be all fingers and thumbs as in anything new whether its flying, skiing or whatever. Suddenely it all clicks and then it all becomes instinctive.
We are taught to climb and descend but what about trying that with your hands off the control column?
ie just use the trim wheel to control the aircraft in pitch.
Trim it to climb. As you approach your level trim it to hold that level.As the speed builds the aircraft will try to climb. Still using the trim wheel only keep trimming forward till for a given power setting and stabilised speed the aircraft holds level.
Now trim forward for a descent again as the aircraft accelerates the tendency will be for the aircraft to pitch up. Look at the VSI and try and maintain the VSI on say 500 fpm down playing with the trim to hold that.
Do this to practice getting used to using the trim wheel and understanding the effects its a good exercise.
