Loading Very Slowly

The night before last my site had been loading just fine then yesterday it became extremely slow. I hadn’t changed anything on the site that might lead me to believe I did something. It seems to just be wordpress that is loading slowly because my other subdomains are loading very quickly. Has anyone else had this problem and if so what can be done? I looked around already that the other posts and they weren’t very helpful. Here is my site. Please let me know if anyone can think of anything to help.
