My girlfriend is almost a month delayed. She has irregular menstruation. Her last was on Nov. 14. And it is Jan. 6 today and still nothing. We have unprotected sex but we do the pull-out. Sometimes we don't pull out during after her period because I thought it was safe. We had a home pregnancy test on late December and it came out negative though we are still thinking whether we should try another test because of her period being so late. She has light nerve showing on her right breast. Is this a sign that she's pregnant?

First of all, your method of birth control is terrible. You're taking a big risk that your girlfriend will get pregnant, because sperm cells can be released even before ejaculation. Secondly, your girlfriend can still get pregnant during her menstrual cycle. My advice would be to go to contact your local Planned Parenthood office for birth control counseling. You all are going to end up with a baby you can't afford to take care of, which would be very unfair to the baby. Lastly, this is the reason parents tell their children not to have sex until they are mature enough to handle the potential consequences.

We were doing it for almost 2 years before this happened. Now she has this spots on her legs I don't know what it is. Is it a sign that she's really pregnant?

The 'light nerve on her breast and the spots on her leg' are not symptoms of pregnancy. Get her to her GP/clinic and do a proper test. I think perhaps, you both need to ask yourselves if you are ready to be parents... this is a very demanding role and you will both serve it for the rest of your lives. Good luck to you both :)
