10 days late

I know taking a test wouldnt hurt but I just wanna see if people have experienced the same. Weve been using condoms for almost 8 years now. I'm currently 10 days late. During the lockdown 2021 i have been delayed for 8-9 days too. I'm currently stressed & I've been sleeping for less than 7 hours couple of weeks ago due to my flights (I work in the airline industry) my bf kept on reassuring me that theres nothing to worry about because he would always check. Right after he would come, he wouldnt stay longer than 3 seconds inside of me, he would slowly remove his thing then remove & check the condom afterwards. :/ Idk how to remove stress aside from taking a test. I also have an upcoming training with exams and I can't fail. Nwbdjdnld :(
