Stress or preggers?

I just recently got promoted and the stress hasn't stopped. I'm normally never late but last month I was 11 days late and this month I am 14 days late. I am sexually active but the last time my S/O and I had sex we ended up getting interrupted and there was no finish.. Lol but I'm not too sure if there's a delay in my cycle because of the stress or because I could be pregnant, please help with your opinions, it would be greatly appreciated! Thank you. 💞
