It won't hurt you if you send them now and you'll save a couple dollars. I can't remember for the SAT but for the ACT it is 12 dollars to send and if you don't buy the 16 dollar priority shipping, they won't send your scores right away they send em out like 2 times a month so you have to wait until one of those times come. That could be an issue if you're under a time crunch. I had some good scores and some bad scores but I sent them all 6 of my standardized tests. Plus, yes there is the "what if I do bad" but you can also think positive and say "what if I do awesome" and you would've wished you sent the scores.
