Pregnant and don't wanna be

Okay me and my boyfriend had sex and the condom broke. He went to Walmart to get plan b and I took it 30 mins after. I do not want a baby at this time and it's kinda an inconvenience to have one. so I was just wondering What are ways to make sure I'm not pregant and if I am how can I try and induce a miscarriage? Is that even possible? I know about like abortion and abortion pills but what's safer and easier? What all can I do to not be pregnant if I am? I have to wait to take test sicen this just happened yesterday. Thank for the help!
