If fetal development is poor in the early stages of pregnancy, how long will it take for a natural miscarriage to occur?

Patient's question:

No

Doctor's answer:

Natural miscarriage often happens on its own around three to four weeks. Miscarriage due to fetal demise is not considered a natural miscarriage; it is a missed miscarriage, usually showing bleeding symptoms after the 10th week of pregnancy, followed by the discovery of fetal demise. You don't need to constantly worry and fear; you are pregnant
