Might be prego.. help.

I️ started my period on June 28, ended on the 4 of July, and had sex with my bf on that exact day I️ was getting off my period. I️ had to take plan b but keep n mind I’ve taken plan b multiple times I️ know it’s not a birth control pill or none of above. Bad choice . Ik. Now I’m facing a different situation, i usually have my period like once a month, I don’t keep track of my cycle, I️ got my period like maybe a week early which I’m currently in, I️ started on Sunday the 15 of the same month I️ ended my last period .. is this a possibility of me being pregnant ? Or is my body just going through a different situation
