Girlfriend already ovulated. condom broke, went and got plan b one step 30 min later. will it work? i just need some assurance, so nervous..

Dad?: Plan b is very effective and was used as intended. For an emergency. If she is several days past ovulation, then that in and of itself is the best chance of not getting pregnant. Most women ovulate about 14 days before their period. There is a technique called natural family planning that is common amongst catholics. That works well. Especially if you are using condoms. Consider ocp as well.
