While having sex with my boyfriend the condom ripped and neither of us noticed until after he came. I'm not on any birth control because we've been having sex with condoms for a while and nothing bad ever happened. We immediately went to get the plan b I took it maybe an hour after it happened. They say it's more effective the sooner that you take it but I also noticed that it says it won't work if you're overweight and I don't even know my weight but I feel like I'm not in the range what do I do!!!!!!?
