System font blink on start

Hi there,

I am experiencing a new glitch on my site since redoing code after a system error wipes everything. Everything worked fine last week. I think my custom font codes are the issue (I think I coded them correctly) but I am not getting an error and they do eventually load properly.

Is there a way to prevent this new lag that is happening when the system font loads and then my custom font loads a second afterward? Should I put the code in the header or something? Or does my code need to be tightened up or something? There is a lot happening in my heading on my homepage but this issue is new.

Let me know if anyone has fixed this issue.

Thanks loves xx
