I'm slightly worried?

So it's been three days since I ovulated and my period begins in nine days. My boyfriend and I messed around tonight and, while we didn't have sex, he rubbed his penis near my vagina (closer to my urethra) and I'm not 100% sure but he MAY have gotten precum there. I urinated right after I told him to stop, just in case. Is there a high chance that I could have gotten pregnant from the precum?? Need to know asap!
