Hi,
Welcome to Health Care Magic,
I am Dr.Naveed Ullah khan,
I have read your question in detail and will try to help you in the best way possible.
Sudden drop in the level of serum
hCG level indicates non viable fetus or there has been a mis carriage. In both cases it is very important to remove all the tissue from the
uterus doing D and C as it can be dangrous and can cause infection
thrombus and possible emboli in mother's blood.
I am really sorry to say and strongly suggest not to wait any more. Do an
ultrasound again and remove the tissues.
I hope this answered all your queries, if you have more queries,I will be happy to answer.
Wish you the best of health.
Regards.
Dr.Naveed Ullah Khan.
