Hi @Snicole25
To me checkout loads fine, no loop or issues. Have you replicated the issue on your side? Did you check in different browsers? Also do try to open your site in a new private/incognito browser window.
Some hiccups with checkout happen sometimes but then also try to check on https://www.shopifystatus.com/ is there some global issue.
You did not ask for feedback but I must tell you, your logo on the checkout is huge. It pushes more important things down. Plus it is different from your logo on other pages. It should be the same.
