I had a transvaginal ultrasound, diagnosis is normal sized anteverted uterus with thickened endometrium (17.6 mm), normal both ovaries, no free fluid in cul de sac, with a positive pregnancy test, suggested follow up in 2 weeks? what could this mean?

Pregnancy prior to: 4-5 weeks or so may not be detectable on ultrasound, generally a repeat scan in a week or 2 will detect the gestational sac if this is the case. Correlation with serial serum quantitative HCG is often performed, since the HCG levels correspond to gestational age, this can help diagnose an ectopic pregnancy or spontaneous abortion, the other main considerations of "empty" uterus and pos preg test
