Hello and welcome to Healthcare Magic. Thanks for your query.
A gestational sac
should be visualized by trans-vaginal ultrasound
by the 6th week. Since your HCG
levels are progressively increasing, in the absence of a gestational sac, there could be two possibilities: one is a miscarriage
and the other is a molar pregnancy
or gestational trophoblastic disease
). A hydatidiform mole is a growth which occurs inside the uterus
which produces HCG (thereby giving positive pregnancy tests
) and can also result in all pregnancy symptoms. Please check with your obstetrician if this possibility has been ruled out.
