plan b again? PLEASE help :(

so i took a plan b this morning from an accident on the 22nd and this evening the condom broke after he ejaculated. should i take another plan b or will the plan b still work from me taking it this morning. please no judgement im just wondering if it will work. my period is expected on the 31st so im exactly a week away from my period. wasn’t sure if plan b would work or not if you’re week away from period. and yes i am trying to get birth control. my dr can’t see me until the 7th of november. i’ve been having cramps today as if my period is coming. my last period was 10/3.
