After dating for a year and 2 months my girlfriend and I had sex for the first time about 20 days ago. We have had sex 5 times since then and today she told me she is 4 days late. What should we do? About 2 months ago her father approached me and had a very serious discussion about how i am not to have sex with his daughter and if she tells her parents I will never be allowed near her again. Weve been together 15 months now and I dont want her parents knowing if shes not pregnant. (we are 16)

My question is what are the chances of her being pregnant? She is now 4 days late and wont really talk to me lately. We used a condom every time and they never split. I remember someone telling me that a delayed period is the result of the stress she delt with losing her virginity. Any truth to that? How long should we wait for her period before we really panic?

When is a good time for her to take a pregnancy test?

Ive been trying to comfort her leaving her voice mails telling her she isnt pregnant and its just from stress but she wont respond to me.
