My hcg level was 12000 at 5 week 2 days but after 72 hrs its only 12500. I went for a transvaginal usg at 5 week 4 days and they saw a yolk sac meseauring 14.4 mm. I want to know is there anything not normal?

As you get further along in pregnancy and the hcg level gets higher, the time it takes to double can increase to about every 96 hours. Caution must be used in making too much of hcg numbers. A normal pregnancy may have low hcg levels and result in a perfectly healthy baby. The results from an ultrasound after 5 -6 weeks gestation are much more accurate than using hcg numbers. An hcg level of less than 5miu/ml is considered negative for pregnancy, and anything above 25miu/ml is considered positive for pregnancy. Yolk sacs larger than 6 mm are usually indicative of an abnormal pregnancy. Failure to identify (with transvaginal ultrasound) a yolk sac when the gestational sac has grown to 12 mm is also usually indicative of a failed pregnancy.
