<s>[INST] hello.. i am 6 weeks pregnannt.. had brownish spotting today morning went for an ultrasound but doctor said she could see a gestational sac of 14.5 mm and a yols sac but no fetal pole or fetal heartbeat.. is it normal? she said the growth is very sluggish...please help i am very tensed.. [/INST] HI,    Thanks for your query. I understand your concern.    At 6 weeks  gestational sac , yolk sac & fetal pole are seen. Heart sounds may appear a bit later .     You don't have fetal pole & have brown discharge too.Possibility of blighted ovum should be confirmed after repeat scan after one week.when both yolk sac & heart beats should be seen .    Thanks. </s>
