Is it normal to see a sac without fetus in early pregnancy?

Question

Hello doctor,

Two weeks ago I had 10 positive home urine pregnancy tests. I consulted with my obstetrician and they sent me for two blood tests 48 hours apart. The blood test showed my hCG level more than doubled within 48 hours which the obstetrician said was great. Well because I have irregular periods I did not know the date of my last period, so my obstetrician scheduled me for a vaginal ultrasound today and the ultrasound showed a gestational sac but no fetus in it. My obstetrician asked me to get another blood drawn in which results came out good and normal. She has asked me to come and do another ultrasound in two weeks to see if they can see the baby. Is it normal to not see the fetus and just the gestational sac in early pregnancy? I have been so nervous and going nuts since my obstetrician did an ultrasound this morning. It is driving me insane. Please send me any information if you can. Thanks so much.

Hello,

Welcome to icliniq.com.

In early pregnancy, by six weeks of gestation, the gestational sac is often not seen and only decidual reaction can be appreciated in the uterus, but as the hCG levels are doubling, there is definitely a viable ongoing pregnancy either inside or outside uterus, so a repeat ultrasound after two weeks shall establish the location and presence of a sac, considering that it would grow to a recognizable size in next two weeks. My concern with you is that you have been on the Adderall tablet, which is a pregnancy category C drug and not to be used before or during pregnancy as it has been known to cause congenital defects in fetuses.
