Help im stressing out !!!

So me and my bf had sex and he cum without knowing and the condom had broke when i got off so I started stressing and the next morning we went and got a plan B and i took it when i got home (i was in the beginning of my ovulation) so after a few days nothing happend and i felt fine and then (in the middle at the end of my ovulation) i woke up and there was blood everywhere I started to stress and put on a pad because it looked like my period but it didn’t look like spotting and it kept on for about 4 days and now im late 8 days for my period

So did i miss my period or already had it ?

Can somebody please help me
