Can I get pregnant from this??????

Okay so I know I shouldn’t worry to much but on Saturday I messed around I didn’t have full on sex he was at the opening of me he never came and was soft the whole time but I’m worried if there was pre cum we used a condom but what I’m mostly worried is if he put it on right like did anything cross contaminated like pre cum if he put the condom on wrong eve says that I was also ovulating that day what are my chances ??? I’m like really stressing out about it
