Hallow Dear, When you have been diagnosed pregnant clinically as well as by ultrasonography, the diagnosis is certain. Clinical estimation of duration of pregnancy is based on the date of last menstrual period (LMP) while ultrasonography estimates it by the size of the baby. Therefore the estimation of ultrasonography is from the day of conception which is about 2 weeks after the menstruation. Hence, there may be discrepancy of about a week or two between clinical gestational age and that by ultrasonography. It is very difficult to visualize baby and baby s heart sounds at 5 weeks duration. Repeat ultrasonography after about a week or more will clarify the picture. So shed off your stress and be ready for the next scan. Inj. hCG and Gestone are prescribed to you to stabilize the pregnancy. You need not be apprehensive about them. Folic acid that is prescribed to you helps the growth of the cells of the baby. It is a good supplementation. I hope this helps you. DR. Nishikant Shrotri
