Month late with my period, but haven't had sex! What could this Mean?

I'm a month late, but I haven't had any sex. I'm really bloated but other then that nothing! What can be happening?

if you are stressed or lifestyle changes or sometimes just cause your body will be late with a cycle
it is not uncommon
relax and it will come
