Is is safe/ okay for me to eat!?

Stephanie • Happily married. 💜 25 years young. Mommy to Maximilliano (7-9-16) and Maverick (10-3-18).
I am really super badly intensely craving a Tuna Sub from Jimmy Johns. Like I'm on the verge of crying if I don't get one. (These darn pregnancy hormones.) is it okay for me to eat one? I haven't had time at all since I found out I was Pregnant. I am 17 weeks pregnant tomorrow. HELPPPPPP 😩
