I just think it's crazy how you have these irresponsible teenagers having unprotected sex and then BAM surprise pregnancy. But then you have people who track, have test strips, keep very detailed calenders to try to get pregnant, AND THEY STILL DON'T GET PREGNANT. like how is it possible that some people happen to accidentally have sex at the perfect time during their cycle and don't even want to be pregnant. But the people who really do want to get pregnant just can't.
