How soon can a pelvic ultrasound tell if your preganant? Can a corpus lutem be a early sign of pregenacy? Can a ovarian cyst be a very early sign?

In brief: 4 weeks

Earlier ultrasound can show signs such as thickened endometrium but pregnancy cannot be confirmed until a gestational sac is seen.
A yolk sac & embryo are more diagnostic but may not be seen until later. An HCG level of 1, 000 should correlate with a gest sac. A cl or ovarian cyst occur with ovulation so are not early signs of pregnancy. Take care.
