Pre-cum
can get you pregnant.
All it takes is onnnnne little sperm.
If you're a week late on your period,
it'd be ok for you to go ahead &take a test.
Take it with first morning urine for most accurate results.
You don't need a parents permission to get a pregnancy
test. Just run to walmart or walgreens &get one.
If you don't want to get pregnant,
get on some birth control &use condoms.
If you aren't ready, the risk isn't worth it.
