Tell her to go to an OB/GYN and have the doctor discuss everything openly with her/him also. Trust me they have heard just about everything and understand. I also would have her check to make sure she did not contract anything from having unprotected sex. The doctor can help with that discussion and testing as well.
If you are a good friend you can go with her to hep make it an informative yet light hearted discussion with the OB/GYN.
Good Luck.
(btw, IMO it sounds like she does not want ot have a baby. That 'should' be discussed with the doctor at the time of the visit and you can let the office know that this is something that need sot be talked about right away. On all counts.
Again, Good Luck,
