Hey Katherine,
If you could share the URL of your home page, I could likely tell you what the issue is but if you don't feel comfortable doing that, here are a few suggestions.
1. Install the "Link Redirect Trace" Chrome extension. An awesome extension that gives you the HTTP headers on every URL in real time.
2. Check for some pretty standard domain redirect issues such as:
-http://example.com to http://www.example.com
-http://example.com to https://example.com
-https://example.com to https://www.example.com
The http to https redirect is very common due to old links, the habit of typing http, and the fact that browsers still default to http unless you specify otherwise.
For instance, if you type example.com in the nav bar, your browser will assume you mean http://example.com and try that, at which time you'll be redirected to the https version.
The .htaccess file (if you're on apache) can be a good place to fix the issue once you know what is happening. It's also worth noting that redirects on your home page are not necessarily a bad thing as long as they're one of the aforementioned examples and they're 301 redirects.
I hope this helps. Let me know if you have any questions!
