The best two ways you can check if all the products you expected are loaded in your store is like this:
From your store, click on Catalog. The url should look something like this: https://<your-store-name>.myshopify.com/collections/all. You should see the total number displayed above the item prices.
From your store admin, click on Products. Then add “/count.json” to the end of the url you should see at the top of this page. It should look something like this: https://<your-store-name>.myshopify.com/admin/products/count.json
… and then after you tap “enter” you should see your product count
