Opinions?? Really appreciate!

Had anal on 13th, he accidentally goes into the normal hole once, he finishes in the booty. Peak ov test was mid morning on the 14th. Took Plan b before I even took the ovulation test just bc of the slip up. Period supposed to start in the next couple of days. How worried would you be about being pregnant? No birth control because the pharmacy had to order it. I understand “if I’m worried wear a condom blah blah” So don’t waste your time answering like that. I’m really wanting an honest opinion about the actual question. Not what I should have done or could have done. Too late for that.
