Worried after sex

So I snuck out with my crush for midnight sex a few days ago and we went two rounds. First round he didn’t use a condom but he pulled out and he said it got all over the seat. The second round he used a condom. I asked him if he is positive I’m not going to be pregnant but like idk I still worry like I’m not on birth control I don’t have any access to taking the morning after pill and I can’t tell my parents cause they would absolutely kill me...is there anything I should try to do to make sure I’m not pregnant or any signs I might be or something?????
