Should I wait to send my AP score to my college?

I bubbled in my college’s school code when taking the 2018 AP Statistics Exam but apparently it didn’t go through. I just recently finished my 2018 AP Exams and I made sure to bubble it in but I still haven’t fully sent in my AP Statistics score. Should I pay the $15 dollars now or should I wait just in case they aren’t sent in for me?
