My web page appears with half of my domain. http://chilbirth.homestead.com/pat.html. My domian is www.childbirthmiami.com

I've tried to publish at least six different new pages for www.childbirthmiami.com. This is an example of what will appear. I have cut and paste the attempted url, www.childbirthmiami.com/pat.html. Strill get error, "Problem loading page..."
I have spent so much time with these problems. Homestead has not been helping me correctly.
Please adise.
I would also like to delete any domain which isn't childbirthmiami.com, www.childbirthmiami.net and joannielsenmchale.com. I seem to have trouble with each of these.
Thank youi
