Plan b pill

Can someone with experience with plan B pill help me? I don’t need mean comments about “read the side effects”. I took the plan b pill like an hour or so after sex. We used a condom only but it fell off. Not sure when. I took the plan b pill a week ago, and now I’m bleeding kinda light off and on for hours. I’m nauseous. I’m dizzy. And I’m cramping a little. It’s way too early to be my period (13 days early). I took the pill, but I was very close to ovulation. I’m terrified I’m pregnant. It’s too soon to take a test since it was just a week ago, and I’m far from my periods date. But the bleeding is making me so nervous. I know the side effects. I need personal experience and advice.
