My girlfriend went down on me and i ejaculated in her mouth.after a couple of weeks, she confessed to me that she putthe semen from her mouth in her vagina and that she waspregnant. is it possible?

Possibly: Unlikely but it is possible. A paternity test will confirm if you are the father.

Don t know: We can not tell if this is true in this case, but is possible. Dna testing will clarify this situation eventually, and testing will confirm the pregnancy. Good luck to both.

Unlikely: It is very unlikely that your girlfriend is pregnant from that sexual interaction. Besides the exposure to the mouth flora and other secretions, you would have to use some pretty sophisticated techniques to get pregnant other than the old fashion way (vaginally).
