Panicked at 17 weeks

I did something today that I regret and now I fear that my baby is in danger.

I am 17 weeks pregnant and today I caved into one of my cravings: I had half of a bagel with cream cheese and smoked lox. I only had half when I started to panic and now I am terrified that this will harm my little girl :(

Has anyone else eaten smoked lox and been okay? I know I was really selfish and made a terrible decision, but I want to know how much danger my daughter is in.
