@Sophia553 Any new host with only a few reviews may struggle against established listings with a good track record or reviews. Basically you are a higher risk for guest until you prove yourself (which you are doing judging on your reviews).
Can I just check how you are checking your pricing? Ideally you will be pretending you are a guest and then search in your region and compare the price of your place against others. This will show how you compare after all the fees and taxes are added to your nightly rate. Also check competitiveness for 3 night and 7 night stays.
After that patience is probably the best bet.
