Pregnancy from precum 2 days before your period?

If you fooled around 2 days before your period and then again a couple hours before starting your period and there was a little bit of precum on the guys boxers but his penis was no where near my vagina and he says he didn't touch the spot but im worried he may have touched the spot on his boxers and continued fingering me and he didn't ejaculate at all for about a week or so and I have a normal heavy period what are the chances I can be pregnant
