Tuna sandwich from subway - pregnant

Edit: I am not worried about eating tuna, I know you can eat 12 ounces a week. I’m worried because the tuna tasted OFF.

I’m having a ton of anxiety. I’m 15 weeks pregnant. My SO brought me home a tuna hoagie from subway.. it tasted a little off but it smelled fine so I figured it was okay and I ate it. Now I’m regretting this decision to eat it because I’m worried about food poisoning and birth defects/miscarriage. Someone reassure me .-. It’s been an hour since I ate it & I feel fine so far.
