Hello doctor! I went for an ultrasound on November 13, 2020 and the doctor told me I was 6 weeks pregnant, the gestational sac was small compared to my gestational age. The doctor prescribed me medication and scheduled another ultrasound in 2 weeks. So I would like to ask the doctor, is it okay if the gestational sac is small compared to my gestational age at 6 weeks of pregnancy? I had my period on September 17, 2020, my period is irregular. This is my second pregnancy. Thank you doctor, I am very worried!
