Please no judging I know I should no better but is this hurting/killing my baby boy,

I'm pregnant with my second baby and all my cravings have been is soft drink and take out mostly burgers with tons of mayo and onion, I have had a few healthy meals in between but I'm so worried that its hurting my baby, I'm stopping from now but have I already done damage?? I'm 19 weeks today and just so terrified as I haven't yet felt he's kicks in this pregnancy,hoping he starts soon so I can always be sure he's okay
