*HELP* TMI

I got my period after plan b for 10 days straight.

I bled very lightly almost spotting the first 3 days and then had a very painful medium/heavy flow with blood clots for the next few days and then back towards the last days I had a light period with dark blood.

It may sound stupid but there’s no possible way I could be pregnant right?? I know I’m not but I still always have the doubts.
