Do you think that an hcg level on apr 14 of 958 and then one on apr 23 of 14885 indicates a blighted ovum. the ges sac is present at 5weeks 5days.

US is more accurate: There is a wide range of "normal" beta-hcg levels. It is difficult to draw meaningful conclusions based on the 2 numbers you provided. If dates are correct, a transvaginal ultrasound should show a yolk sac and fetal pole by 5 weeks 5 days. It could be the dates are off a bit in which case it may just be too early. A follow-up ultrasound can determine if this is a viable pregnancy.
