Deli meat?

How do y'all feel about eating at places like Subway when pregnant? 
During my last pregnancy I craved Subway all the time, but I didn't eat it. So after I have my little I immediately asked for a subway sandwich and the nurse told me that it would have been ok for me to eat one every now and then while I was pregnant. 
This time around I ate one and now I feel kind of guilty about it.
