Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
According to your description the possibilities are :
-Usually fetal heart beat can be seen by 7 weeks of gestational age
So, if previously heart beat is seen and missing now, there is possibility of missed abortion
-If heart beat not seen till now, there is possibility of blighted ovum
, in which yolk sac only develop with absent fetal pole
In both the cases, the possibility of pregnancy
is very less and you may need to terminate the pregnancy. Medical termination is possible when the decision is taken early.
Please discuss with your doctor and proceed according to her advice.
Hope I have answered your query, I will be happy to answer any follow-up questions.
