I am 10 days late

Back in April my bf and I were fooling around. There was no penetration and he didnt cum anywhere on or near me. But his penis was rubbing on my vagina and there might have been precum. He didnt ejaculate before than and even if he did he had urinated a few times. Anyway so this happened 3 times in april and the last time this happened was on the 24th of april. On the 28th of april i got my period which from memory was normal.

Ever since then we haven done anything except fingering and that too before he ejaculated. It is now the 5th of june and I am 10 days late :( I got my blood test done last wednesday (1st of june) and the report came back negative (hcg level was zero)

But my period still isnt here and i'm usually regular. I'm freaking out so much, is there a chance i could still be pregnant????
