please help

i had sex about 4 weeks ago, we used condoms but one broke (he hadn’t cum yet) ... the second it broke we put another one on. i didn’t get a plan B because i had taken one a few weeks before. i also did a lot of research and it said you can’t get pregnant from precum unless he had recent cum which he hadn’t. i look a digital test a week ago and it said Not pregnant but i’m afraid i took it too early. i have a very irregular period so i’m stressing and i feel like i’ve been peeing more and my boobs are a little sore. should i be worried? should i trust the test i took or take another one? please don’t be mean i’m already stressing enough.
