This is so incredibly stressful.
The bolded portion is 100% correct. As others have said, wait and see how it ends up graded. In my experience (as a student, TA, and with a number of friends in academia), instructors are quite good about awarding partial credit when they see that you comprehend the concepts and processes but missed some bit that creates a domino effect for the rest of the problem. If it turns out that your professor doesn't approach it that way, I don't think it's inappropriate to speak with them about it in person
, assuming you can do it without whining or sounding like you feel you're entitled to a higher grade. However, preemptively contacting them and trying to explain your mistake isn't the right way to go about it.
