How many 12 year olds get pregnant in 7th grade?

It depends... is she sexually active? If not, she won't get pregnant. At 13, everything works in most girls and she can certainly get pregnant.

though it is completely possible to become pregnant at thirteen, usually if it was your first time, the stats show 1 in 20 girls get pregnant when not using protection, that is more of a common stat when using the with drawel, ethod, and stats can always change, pregnancy scares are the scariest i know i have been through it, but i would wait unil you miss your period, if that happens take a test, they are about 15 dollars for a single pack, 20 for a double pack, remember since you are so young your periods may be quite irregular if so wait for two weeks after possible conception, and take a test, 13 seems a little young and remember if you do not want to get pregnanti would abstain, or use better contreception, like use a condom all the way through,
