Thanks for writing in HCM.
Urine test of pregnancy
has 99% accuracy. Urine test may be false positive if you are taking some medicines like phenothiazine
. In ultrasound if one sac is visible then it gives you the cofirmation of gestational sac
. For more confirmation You can do your HCG
hormone level. HCG levels will double every 72 hours. The level will reach its peak in the first 8 - 11 weeks of pregnancy and then will decline .You can repeat your transvaginal ultrasound
after 2 weeks for viability of fetus. for further advice consult your gynecologist.
Wishing you a good health.
