Update:
Still trying to troubleshoot this issue and have discovered another strange thing that happened at the same time...
I have two websites, one is in a subfolder... at the same time as I stopped receiving the emails for my main site (http://www.slightlylostgirl.com) I began receiving the emails from my subfolder site (http://www.lachicapaleo.com) at a different email address than usual. I am no longer receiving them at my normal admin email but rather my email that is registered on wordpress.com could this be a jetpack problem?
