Due to some unforeseen obstacles in my life I wasn't able to pick up Luxie at 12 weeks old and will pick her up at 15 or 16 weeks, I'm so sad that I can't pick her up earlier

I am BEYOND SAD.
But now I'm also worried!!! Will this affect her socialization? I know that puppies leaving too early or too late have socialization issues, and I will be picking her up too late I guess
Will she turn out normal? I will love her even if she gets difficult but of course if I can prevent from getting aggressive towards people or other dogs I'll do it. What should I do? Is there nothing I can do at this point?? There's still hope right?? Any advice?? Please help!! <3
