Is pregnancy possible in my situation?

My boyfriend and I had sex on June 3rd. The sex was only about 2 minutes long (he also did not go all the way in) and he used a condom. The condom was on the entire time and he did not ejaculate until later when i was fully clothed. There was also no precum because it was wiped off before hand. But is it possible that i could be pregnant? Im supposed to be getting my period on the 23rd of this month and i was not fertile or ovulating when we had sex. I have heard that stress and anxiety can cause a period to be late which also worries me because my grandfather recently had a heart attack which has made me pretty stressful and not only that but i have also been anxious about being pregnant. Is pregnancy very much possible in this situation? and could my stress and anxiety cause my period to be late?
