Early USG scan (abdominal) at 5 weeks may not reveal detailed view about fetal pole
or cardiac activity. Basically it is seen around 7-8 wks in case of USG scan and around 6 wks on TVS scan. So it is better to undergo one TVS scan for confirmation of fetal viability and cardiac activity after 2 weeks as per your doctor's recommendation. Otherwise it may turn to miscarriage
due to blighted ovum
. Further consultation with gynecologist is needed in such cases.
Take folic acid
supplements, protein rich healthy diet, avoid long journey/heavy work, maintain personal hygiene, take adequate rest. Be well and take care.
