I understand your concern.
-The series of events & investigation reports suggest possibility of an early fetal loss / chemical pregnancy/ missed abortion. This is a condition where a non viable pregnancy stops progressing, but the hormones production does not stop. This makes late +ve pregnancy test , a less rise in blood hormones(chorionic gonadotrophin) & fetal growth arrest with no heart beats.
- To avoid haste & wrong diagnosis, your doctor has advised to wait & repeat sonography after 1 week.
- There is nothing to be tense about. Such thing happens once in while. Though you need some precautionary investigations/ treatment as per your doctor's advise.
-With proper care/ medical guidance, next pregnancy will be normal.
