It is quite natural to have such an apprehension after 3 previous miscarriages. If your cycles were regular, you should be having some 8-10 weeks gestation now. Typically, such a sac shows a fetal pole
and fetal heart. Yet, a single sonogram cannot decide anything, so you need a repeat ultra sonogram as advised. As per precautions, avoid intercourse and stress
, take as much bed rest
as possible. Dietary advice includes fresh fruits and vegetables, plenty of diary products, nuts and whole grains. Some herbs are supposed to help in preventing an abortion
, but they should be used with caution. Please ask your doctor if any hormonal
supplementation is needed. Take care.
