Help me please

Okay so my last period ended on October 29th and then the next day me and my boyfriend had sex, he wore and a condom and he still pulled out but the condom broke as soon as he pulled it off but nothing got inside, the next day I took plan b just to be on the safe side. And then I think I had my period last week November 6th-8th but it wasn’t my “normal flow” the first day it was like brown color and I googled that if it’s brown then it’s old blood and then the next day it was red and heavy and then on the last day it was red and light.

What do y’all think?
