thank you alot for the help and advise
Than she's not pregnant.
Stop having unprotected sex.
we did a scan 22weeks after having intercourse
i had intercourse once with her in 06 january 2010
and did a scan on 09 june 2010 at the gp it was a some black and what machine that can see a females womb it showed empty nothing was inside her
Unprotected sex is EXTREMELY foolish. Pulling out is NOT a reliable form of b/c and it CAN get a girl pregnant if she's ovulating. ALWAYS USE CONDOMS!!
If she had a scan done at 13 weeks and you saw nothing she's not pregnant. By 13 weeks you'd be able to see a developing baby.
it sounds like you made a mistake and took responsibility for it. i am a little confused, you say 22 weeks since 01 JUN 2010. i think it may be about 13 weeks, and if the ultrasound shows nothing in the womb the young lady is probably not pregnant. (you can see the sac the baby is in at 1 week). you may not have much contact with her, but if you hear or notice that she may be having pregnancy symptoms, you would need to talk to her about it. these could be signs of some problems that i won't talk about here because you don't need to worry about them at this point. good luck.
