Anyone else????

Had a bad diet whilst pregnant and their baby be okay? I have 3 weeks left and hardly ate anything healthy at all i drink healthy but not eat now I’m panicking I haven’t got diabetes or anything I’ve been checked but now I’m worrying my baby’s going to be unhealthy because of my diet

I drink 3 litres of water though everyday and I eat sometimes fruit but my food has just been crap not suger but stuff like pizza,burgers and stuff like that I haven’t ate healthy meals
