How big is the chance of fetal heartbeat, fetal bud, and fetal arrest?

Patient's question:

No

Doctor's answer:

Throughout the entire pregnancy, if the fetus is affected by adverse factors, there may be a possibility of miscarriage, premature birth, or adverse outcomes. Generally, after the fetus has a heartbeat, its development tends to stabilize relatively. Fetal demise may not necessarily present symptoms, and regular prenatal examinations are key.
