welcome to healthcare magic forum
U have not mentioned the reason for why the fetal heart beat was absent, or did your doctor not explained.
Anyways dont get disappointed consult a senior gyenic she will go through some blood tests like thyroid
profile, torch tests, pelvic sonography
or any other as required. after knowing the cause treatment will be planned accordingly and hopefully u will conceive. Take care.
