Girl at first they will prob be mad... I wuz 17 when i got pregnant wit my first kid.. but i did not have to tell her she knew right off... but just tell them they cant kill ya or nothin... it will be ok
1st thing clam down one thing at a time.You should tell them but first u should talk to the dad and what do you guys want to do.Than go to them and talk mabout the plans that you have come up with.
Good luck
