help i’m hella scared

okay so my boyfriend and i were about to have sex on the first day of my fertile window (7% chance of pregnancy), there wasn’t any foreplay and he just put it in me without a condom for two or three times and then i asked him if he had a condom on and he was like no so we just stopped immidiately. my period is due today and i still haven’t gotten it and i’ve been stressing so fucking much and haven’t been able to sleep. what are the chances of pregnancy ?
