Changed the WordPress URL OPPS

Ya so obviously I’m not good at this website stuff and I’m new to wordpress. I was trying to direct my .ca page to my home page that I created. So I changed the https://tosweekcakes.ca to https://tosweetcakes.ca/home As soon as I did this it logged me out and I can’t get back in. I’ve tried getting in my going to wp-login and wp-admin on both .ca and .ca/home The page also shows up in the wrong format when you visit it. I don’t know what to so now. If anyone knows how to fix it without losing everything that would be great. If my only option is to start allover, I guess I have no choice.. but I still need to figure out how to do it. Please help!

Thanks!
