Hello,
thanks for using health care magic.
Pregnancy test is high highly sensitive after missing
menses on the expected date of menses. Early diagnosis
relies more on blood or urine
HCG testing which is what is
done on home pregnancy testing strips.
Ultrasound in such
an early stage has to be endovaginal ( that is the probe of
the ultrasound has to be put inside the vagina) else there
will be a fair chance of missing to see the
gestational sac.
However, it is possible to have a false positive pregnancy test
but that is in the case of a history of
fertility drugs that contain
HCG or tumours like ovarian tumors.
So in a nut shell, the most sensitive test now is the blood or urine
HCG strip rather than ultrasound. Redo the pregnancy testing and if
its still positive you could do your ultrasound in 2 weeks time.
Hope this helps you.
