I’m not right?

The last time i was with my boyfriend (were long distance) was about 19 days ago. He fingered me and i gave him bjs and hjs. Im scared of precum on his hand that went into me when fingering....I got my period about a week later. It was heavy and lasted for 6 days. I took a pregnancy test 18 days after this itimacy and it was negative. Soo I’m NOT PREGNANT RIGHT!?!
