well your dates maybe off by abit especially if your periods arnt regular, even if they are you can ovulate abit later or earlier than the norm so that can cause your dates to be abit out, good luck :)
Hi thanks for your response, I feel much better my dr said she can see a very faint line but not sure she did a vaginal ultrasound and said I might be less than 6 weeks, im hoping its good news thanks for your response
once hcg leves reach over 12oo I think it is then they slow down and dont double every 48/72 hrs, but with numbers that high you should be able to see more than just a fetal pole, did they do a vaginal u/s these are more accurate than the regular abdominal scans in early pregnancy
