Miscarriage is one of the most common yet least openly discussed experiences in women's health. Approximately one in four recognised pregnancies ends in loss, most often during the first trimester. Despite how frequently it occurs, many women tell me they felt completely unprepared – both for the physical reality and for the depth of grief that followed. I want to change that by offering honest, compassionate information so that if you or someone you love is affected, you feel less alone and more empowered to seek the support you deserve.
How common is early pregnancy loss?
Early pregnancy loss, defined as miscarriage before 12 weeks of gestation, is far more common than most people realise. Current evidence suggests that around 15 to 25 per cent of clinically recognised pregnancies end in miscarriage, with the true figure likely higher when very early losses (sometimes called chemical pregnancies) are included. Many women experience a miscarriage before they have even shared the news of their pregnancy, which can intensify feelings of isolation.
It is important to understand that miscarriage is not rare, and it is almost never the result of something you did or failed to do. Exercise, stress, working, lifting, and sexual intercourse do not cause miscarriage. The overwhelming majority of early losses occur because of factors entirely beyond your control.
Understanding the causes
The most common cause of first-trimester miscarriage is a chromosomal abnormality in the embryo. These are random genetic errors that occur during fertilisation or early cell division, and they become more frequent with advancing maternal age. They are not inherited conditions and do not reflect on your health or your partner's health.
Other factors that may contribute to pregnancy loss include:
- Hormonal imbalances: Conditions such as polycystic ovary syndrome (PCOS), thyroid dysfunction, or inadequate progesterone levels can affect the ability of the uterus to sustain a pregnancy
- Anatomical factors: Uterine abnormalities such as fibroids, a septate uterus, or cervical insufficiency may increase the risk
- Blood clotting disorders: Antiphospholipid syndrome and other thrombophilias can affect placental blood flow
- Infections: Certain infections, though uncommon, can occasionally contribute to pregnancy loss
- Lifestyle factors: Smoking, excessive alcohol consumption, and very high caffeine intake are associated with a modest increase in risk
- Unexplained: In a significant proportion of cases, no specific cause is identified, which can be particularly frustrating
What to expect physically
The physical experience of miscarriage varies enormously from one woman to another and depends largely on the stage of pregnancy. Some women notice light spotting that progresses to heavier bleeding with cramping. Others may have no symptoms at all and learn of the loss only during a routine scan – this is known as a missed miscarriage and can be particularly shocking.
Common physical signs include:
- Vaginal bleeding, which may range from light spotting to heavy flow with clots
- Cramping or pain in the lower abdomen, similar to or stronger than period pain
- Passage of tissue
- A sudden decrease in pregnancy symptoms such as nausea or breast tenderness
If you are experiencing bleeding or pain in early pregnancy, please seek medical attention promptly. While bleeding in the first trimester does not always mean miscarriage – it is relatively common and many pregnancies continue normally – it should always be assessed.
Management options: your choices matter
Once a miscarriage has been confirmed, there are generally three management approaches, and the right choice depends on your individual circumstances, preferences, and medical history. I always take time to discuss each option thoroughly so that you feel confident in your decision.
- Expectant management (waiting naturally): Many women prefer to allow the miscarriage to complete on its own. This can take days to weeks. It avoids any intervention but can be emotionally difficult due to the uncertainty of timing
- Medical management: Medication (typically misoprostol) can be used to help the uterus pass the pregnancy tissue. This usually works within a few hours and can be managed at home with appropriate pain relief and support
- Surgical management (manual vacuum aspiration or MVA): This is a short procedure performed under local anaesthetic or sedation. It is the quickest option, carries a very low complication rate, and many women appreciate the sense of completion it provides
None of these options is inherently better than the others, and your choice will not affect your future fertility. What matters is that you feel informed, supported, and respected in your decision.
The emotional impact and the importance of grief
The emotional response to pregnancy loss is deeply personal and there is no right or wrong way to feel. Some women experience intense grief, while others may feel a sense of relief mixed with sadness, particularly if the pregnancy was unplanned. Many feel guilt, even though there is no reason to. Partners, too, often grieve in ways that may not be immediately visible.
What I hear most often from my patients is that they feel their loss was minimised by others – well-meaning comments such as "at least it was early" or "you can try again" can be deeply hurtful. Your pregnancy mattered, regardless of how many weeks it lasted, and your grief is valid.
I encourage women to:
- Allow yourself time to grieve without setting a timeline for recovery
- Speak to your partner openly about how you are both feeling
- Consider professional support through counselling or organisations such as the Miscarriage Association
- Be gentle with yourself – returning to normal routines may take longer than expected
- Know that feelings of anxiety in a subsequent pregnancy are entirely normal
Recurrent miscarriage: when to investigate
Recurrent miscarriage is defined as three or more consecutive pregnancy losses and affects approximately one in 100 couples. After three losses, I recommend a thorough investigation to identify any treatable underlying factors. However, many consultants, myself included, will begin investigations after two losses, particularly if there are other concerning features or if maternal age is a consideration.
Investigations typically include:
- Blood tests for antiphospholipid antibodies, thyroid function, and hormonal profiles
- Assessment of uterine anatomy via ultrasound or hysteroscopy
- Karyotyping (chromosome analysis) of both partners in selected cases
- Screening for blood clotting disorders
- Assessment of ovarian reserve and other fertility markers
There is growing evidence supporting the use of progesterone supplementation in early pregnancy for women with a history of recurrent miscarriage and those experiencing bleeding in early pregnancy. The PRISM trial demonstrated a benefit in these specific groups, and I discuss progesterone therapy with my patients on an individual basis, weighing the evidence carefully.
Miscarriage is never your fault. It is one of the most common experiences in reproductive health, and seeking support – whether medical, emotional, or both – is a sign of strength, not weakness. You do not have to navigate this alone.
Trying again after loss
One of the most common questions I am asked is when it is safe to try again. Physically, there is no medical reason to delay beyond your first normal menstrual period, although some women prefer to wait a little longer for emotional readiness. The World Health Organization previously recommended waiting six months, but more recent evidence suggests that conceiving within three to six months of a miscarriage may actually be associated with better outcomes.
What I find most important is that you feel ready – and readiness looks different for everyone. Some women feel a strong urge to try again quickly, while others need more time. Neither response is wrong. If you do become pregnant again, I offer early reassurance scanning and close monitoring to help manage the inevitable anxiety that accompanies a pregnancy after loss.
If you or your partner are struggling emotionally, please do not hesitate to seek support before trying again. Your mental wellbeing matters just as much as your physical health, and starting a new pregnancy from a place of emotional strength can make a meaningful difference to the experience.
If you have experienced pregnancy loss and would like compassionate, expert guidance – whether you are seeking investigation, emotional support, or reassurance in a new pregnancy – I am here to help.
