How Many Miscarriages Count as Recurrent Pregnancy Loss?

Losing a pregnancy is painful. Losing more than one can leave couples confused, tired and afraid to try again. One of the first questions they ask is whether this counts as "recurrent" and when to seek help. This article gives clear answers with compassion.

How common is miscarriage?

Miscarriage is common. About 1 in 5 recognised pregnancies end in a miscarriage, and most of these are caused by a one-time chromosomal error in the embryo. This is not caused by something the mother did, such as lifting, travel, stress or an emotional upset.

Two losses in a row happen in about 2 to 5 percent of couples, and three or more in about 1 percent.

How do guidelines define it?

• ASRM (American Society for Reproductive Medicine) and ESHRE (European Society of Human Reproduction and Embryology): Two or more pregnancy losses.
• RCOG (Royal College of Obstetricians and Gynaecologists): Three or more consecutive losses before 24 weeks.
• Some include non-visualised pregnancy losses, such as biochemical pregnancies, while others count only losses confirmed by ultrasound or tissue examination.

In practice, your doctor will look at your age, history and test results to decide when to evaluate.

Does the number need to be consecutive?

Many definitions do not require losses to be back-to-back. Two or more losses, even with a healthy pregnancy in between, can sometimes warrant evaluation, particularly if there are other clues.

Which losses count?

• Early miscarriages before 12 weeks
• Later miscarriages from 12 to 20 or 24 weeks
• Pregnancies lost after confirmed heartbeat
• Sometimes biochemical pregnancies, which are very early losses detected by blood or urine tests

Ectopic pregnancy and molar pregnancy are generally not counted, though they are important events to tell your doctor.

When should you see a doctor?

Seek evaluation if:

• You have had two or more pregnancy losses
• You are 35 or older and have had a loss
• You have had a loss after 10 weeks, with a heartbeat seen
• You have had a stillbirth or a second-trimester loss
• You have known medical issues such as thyroid disease, diabetes, PCOS or an autoimmune condition
• You have had difficulty conceiving
• You are anxious and want guidance

What happens at the first visit?

The doctor takes a detailed history, examines you and reviews earlier reports. They may suggest tests for both partners, covering hormones, uterine anatomy, blood clotting, genetics and other factors. A cause is found in only about half of couples, but even when no cause is found, the chance of a healthy next pregnancy is good, often above 60 to 70 percent with supportive care.

What should you avoid believing?

• That you caused it by working, exercising, travelling or having an argument
• That it was an "evil eye", a sin or bad luck
• That nothing can be done after two losses
• That it will definitely happen again

Looking after your emotional health

Grief after miscarriage is real. Talk with your partner, family or a counsellor. Take time to heal physically and emotionally. A fetal medicine specialist or fertility doctor can support you at each step.

The part to remember

You are not alone, and there is hope. A proper evaluation and careful monitoring give many couples the answer and the care they need. For compassionate guidance, consult Dr Malathi G. Prasad, a fetal medicine specialist at Trichy Fetal Medicine and Fertility Centre in Trichy.
