Pull out method and plan B

my guy and I have used the pull out method and I was ovulating those days according to this app.

Question would be do you suggest to take the morning after pill if he didnt cum in me?

Or should I wait and see if my period will come in september?

Question is rather do I risk taking another plan B in a month or do i risk the pregnancy?

The issue is I would have taken one already but im scared as I took one on the 10th of august because of the condom tearing in me, so there was a higher chance there obviously and I had to in that case.
