Plan b advice??

So yesterday me and my boyfriend had sex twice both unprotected ... first time he came then we waited about a hour then had sex again the first round when he came he wiped off and before the second round I gave him head, I was on my fertile window yesterday with a 33% chance of pregnancy should I take a plan b today just to be safe??

Okay update: before people start saying stuff for having unprotected sex I'm allergic to latex and I was recently adopted so I have no form of Id yet to take myself to the doctors to get on birth control and after this I told my boyfriend I dont want to be having sex until I get on birth control
