This is an early pregnancy
in the uterus
. It is too early for a fetus to be seen by ultrasound
. BHCG levels can be repeated in 48 hours and then again in 48 hours to look for an appropriate rise. Ultrasound can be repeated in 1-2 weeks to look for a change. This may also be a miscarriage
but this cannot be determined until after serial blood levels have been obtained and a repeat ultrasound has been done.
