The 12 teenagers from this season's "16 and Pregnant" were all shocked to learn that they were expecting. Now, they're using their experiences to educate others — and help prevent unplanned pregnancies.
Last week, the girls and their significant others (and in one case, an aunt!) were tested on a slew of topics. Among them: whether it's better to use two condoms instead of one, the effectiveness of birth control pills if you skip a few days, and whether birth control is necessary if you're not in a relationship.
Now it's time for another pop quiz! Can you get pregnant if you have sex during your period? Do condoms have an expiration date? How old do you have to be to buy the morning-after pill? And what makes someone a "freak," according to Savon's aunt LaDonna?
+ Watch the video and take the quiz, then tell us: How did you score compared to the young moms? And to learn more about all the methods of birth control that were discussed, check out Bedsider.org.
