SAT dates?

I’m freaking out right now because, I’ve taken the SAT without essay and Stanford requires it with essay. I was going to take two subject tests (math II and physics) but there are only a couple test days left. Please help me, I know I should have planned better and I feel like such an idiot. I need to take the SAT with essay and as many subject tests as I can. I will take the SAT with essay on Augest 26, but can I do the October 7 test day for a subject test, because the website says they will send the scores within ten days of octobor 31? I know stanford said “We recommend students take the required tests well in advance of the application deadlines. It is unlikely that scores from tests taken after the deadlines will arrive in time for review. We cannot delay the review of an application in anticipation of scores that will arrive after the deadline nor can we guarantee that late scores will be reviewed.” Are there any other dates I could take these tests before november 1? I want to do early application to stanford, but would waiting for regular decision be worth it for the subject tests? Please help me I’m super worried.

Why not the SAT subject tests in August and the ACT with essay in September?
