To cancel or to not cancel…

So I’m a junior right now, and I got a 1550 on the SAT in October. I took it for the second time in December, and I feel really bad about it. I’m almost certain I got a lower score in both sections than my October one. Should I cancel my score? Are there any downsides to doing so other than the slim chance that the score ends up being better than I expected? I’m taking it in March again anyways.
