Had to take Plan B.... super scared now :(

11/30 had sex the condom broke but he said he didn’t fully cum in me but was pulling out as he was. Took Plan B One-Step within an hour but was super scared because my fertile days were coming up in 3 days (12.02). I felt nauseous for two days, mood swings all week, and on 12/05 i started bleeding (12/08 still am) but not really heavy. I still have some occasional cramping, along with occasional lower back pain. Its too early to take a test but I’m still scared I’m pregnant :,(
