Sleeping help for a child

My daughter will be 4 tomorrow April 1. For the past several weeks she has been waking up every 1-2 hours in the middle of the night. She says she can’t sleep or she hears noises. We have tried: books, TV, Music, and melatonin gummies (1mg) at bedtime to help her sleep and absolutely nothing works. I’m exhausted and grumpy as well as she is. I’m in so serious help here. Is this when I should call the doctor and ask for help....I have no clue what to do.
