If she's going to be 16 soon, then depending on your state/province laws, she can get a pregnancy test without her parents ever knowing unless of course something bad happens, then they have to contact family.
Wtf am I yapping about...
Just go and buy one ! They're fairly cheap and she can stick something up her vag that won't get her preggoooo..
I'm srs tho bro. I hope for you that she's not preggo unless ur rdy for it.
If u arent... it's time to grow up and fast bud. Look for some good advice on help lines. I'm sure there are services for that.
Good luckkkkk.
