help!

hey so i had sex like 2 weeks ago, and we used a condom and he didn’t actually ejaculate, but i am just worried that i might be pregnant. i haven’t gotten my period and it’s due to come in 4 days, but i’m just paranoid. i’ve noticed that i haven’t been feeling like myself lately, and that’s mostly why i’m so anxious about it. i’m not on birth control, and i was supposed to start my ovulation that day, so it would have been a really small pregnancy chance anyways, i just need some help since i’ve been worrying like crazy. thank you guys!
