dear all

me and my girl friend had unprotected sex in 29/10/2012 and I did not ejaculated at all, my gfs last pireod was on 17/10. just 22 hours after sex she took Morning after pill and she had symptoms. on 11/11/2012 she had very light bleeding until 15/11/2012 and n tha last day she had brown spott as well. and we thought it was her pireod though she did a pregnancy test on17th it was negative and another one on 21, negative again. and today 27 she had some kind lower abdominal paint with out any breast tendernes or any other paint or bleed. so ist ok?'or is it a sign of something like ectopic pregnancey or what? however she feel little bit tierd. becasue we both are very scared.. looking forward to hear from you
