Could this be the reason for my delayed period?

Hello! I never had sex, just fingering and blowjobs in my bf, he never went in me, yet. Last June 20, my anxiety peaked as I experienced insomnia and was obssesively thinking about bad thoughts for days. I lost 4 to 5 kilos as I couldn't find any energy to eat due to lack of sleep. I got my period around June 26 and started to go out of my house, going to my province, city to city in the span of 2 weeks just to ease my anxiety. I started gaining weight, like 3 kilograms in a week(?) Although I was still stressing about my anxiety because I kept thinking my what ifs but I'd reassure myself sometimes. I was suppose to have my period yesterday, but I haven't gotten it. They're usually early or on time so I'm a bit scared because I keep overthinking I might be pregnant.
