CONDOM BROKE

My boyfriend and I had sex the other night on July 4th, and after it was too late we realized the condom had broke. So we rushed over to the closest Walmart and bought a Plan B pill in a frantic state of worry. After I consumed the pill I figured I would be okay because I’ve had to take it before. The only catch is this is around the time of my ovulation. And I’ve been researching online and now my paranoia is skyrocketing in fear that the pill won’t work. I leave for Air Force BMT in a month and I need any advice or information. Please!!! 😰😰😰
