Can someone help? Im getting stressed

Today is april 15 and im supposed to get my period at april 10. Im 5 days late now. Me and my boyfriend had a sexual activity on april 7. Is it possible to get pregnant just by rubbing genitals fully naked and him fingering me afterwards? I'm overthinking that the precum might slip and enter inside my vagina and even tho he didnt finish inside, near, or on the vagina. Im thinking that its impossible to conceive that way but at the same time Im really stressed since april 7. Am i late because Im pregnant? is it because I got so stressed thinking about it these past few days? Is it because im just late in general? This 2022 all my cycles were 33 days(jan to feb), 32 days(feb to march). Thanks for answering
