am i not pregnant or should I keep worrying ???

Had sex feb 1-2 unprotected, took plan B the day of the 2nd. Had unprotected sex again on the 8th, then the next day bled for 5 days. Took a pregnancy this morning and its negative. I think it’s safe to say i’m not pregnant, but I was reading you need to wait three weeks from the day you last had sex. So do you think it’s been enough time for my test to be accurate??? My period is kinda fucked from plan B and quitting Birth control so i don’t even know where it’s supposed to be. According to glow i was ovulating jan 30-feb 4 or whatever. I just wanna know if i’m totally good or test again in a week ???
