What should a 15 year old male do when he thinks he acsidently got his girlfriend pregnant but not sure and doesn't want to tell his parents and has about 40hours to go to the clinic to get the pill?

You have to talk to some one as soon as possible - is there someone you can talk to that can then later also go with you and talk to your parents ? This is a heavy burden to carry and you need to spread the load. Take Care.
