What does this mean? Need mind at ease

So about a week ago I had sex and unfortunately the condom broke and this was 4-5 days after my period. Not sure if I was ovulating but according to glow it was a couple days away and another app said I was fertile. I took plan b an hour and a half after the incident. five days after taking plan b, I was bleeding (medium flow) for about two days. What does this mean? Should I be worried? What’s the chance of being pregnant. Sorry I’m just stressed and please don’t attack me, my parents refuse BC. Anyone gone through this or going through this?
