protected?

am i protected if i started my birth control pill on march 10th, even tho i didn’t have sex but grinded on my boyfriend (both naked) for not even 3 minutes then he came on my stomach on april 10th, i’m scared of precum even though his penis never went in......i’m scared i’m pregnant bc my back is bothering me and my pelvic area hurts and i keep peeing but i think it’s my anxiety making me so nervous . i took a pregnancy test today (may 6th) and it said negative today. don’t judge.....
