Pregnancy

Yolk sac at 7 weeks

09/30/2009

Question:

LMP was 8-4-09; on 9-1-09 beta was 66; 9-9-09 beta was 439; 9-11 beta was 828; 9-16-09 beta was 4398; 9-18-09 beta was 7227. TVUS on 9-16 gest sac was .8 measured 5w4d only gestational sac seen; TVUS on 9-23 gest was was 1.5 measured 6w2d and gestational sac and yolk sac seen, no HB, area around gestational sac was much thicker than week before. I have another US on 9-30. I had a MC in June 09 and am so concerned and want to know what way you feel this is swaying - viable or not viable. I am very tired most of the time, sore nipples, some nausea, some constipation, bloated a lot. So I have pregnancy syptoms going on. Do you still see this at this stage is the pregnancy is not viable?

Answer:

There is always frustration with early ultrasound to assess pregnancy viability.  There is a range of normal and comparisons to hCG are hard because labs differ in their values.

The US on the 30th will likely yield an answer.
