An early miscarriage usually starts with bleeding, followed by cramping that feels heavier than a period. Most happen before week 12. And in some women there are no symptoms at all, until a scan shows something different.
What I miss on almost every Dutch page about this is the comparison with an ordinary heavy period. That is exactly the question you type in at three in the morning.
Below is how the symptoms usually unfold, how they differ from your period, and when to make the call.
What are the symptoms of an early miscarriage?
Vaginal bleeding is the most commonly reported first sign, often starting as brown or light red spotting that grows heavier over a few days. Cramping low in the abdomen and lower back follows. Sometimes clots or tissue pass. Breast tenderness and nausea from the pregnancy often fade.
That order is not fixed. Some women get cramping first and bleeding later.
At around five weeks the whole thing can still resemble a period. At nine or ten weeks the bleeding is usually heavier and lasts longer.
How does an early miscarriage compare with a heavy period?
The overlap is large, and no single symptom proves anything. Still, some patterns differ: how it unfolds across the days, what passes with the blood, and whether pregnancy symptoms fall away. The table below sets them side by side as a thinking aid, not a diagnosis.
| What you notice | Heavy period | Early miscarriage |
|---|---|---|
| Pattern | Heaviest days at the start, then easing | Often starts light and builds over several days |
| Cramping | Familiar pattern, usually responds to your normal approach | Often stronger and comes in waves, sometimes with back pain |
| What passes | Blood, sometimes small clots | Larger clots, sometimes greyish tissue or a sac |
| Duration | Usually 4 to 7 days | Can continue for one to two weeks |
| Pregnancy symptoms | Not applicable | Breast tenderness and nausea often fade |
| Pregnancy test | Negative | Often stays positive for 1 to 4 weeks |
Imagine you are five weeks along and the bleeding starts light, then gets heavier across 3 days. With an ordinary period, day 1 is usually the heaviest. That pattern is one of the few differences you can read anything from at home.
I will say straight away that this is a clue, not proof. Only a scan settles it, and that referral runs through your GP or midwife.
That last row confuses many women. The hormone hCG clears slowly, so during this window a positive test says little about whether the pregnancy is continuing. What the values themselves show is covered in hCG levels during a miscarriage.
Can you have a miscarriage without symptoms?
Yes. That is called a missed miscarriage: the pregnancy has stopped, but your body has not started the process. There is no bleeding and no pain. It surfaces at a scan, sometimes weeks later, which makes it especially hard.
Nausea that disappeared or breasts that feel less tender often get read as clues afterwards. In practice that is not a reliable signal, because those symptoms fluctuate anyway.
There is nothing here you can measure yourself against. That is uncomfortable, and it is honest.
Does bleeding always mean a miscarriage?
No. First trimester bleeding is common, and a substantial share of those pregnancies continue normally. The 2021 Lancet series on early pregnancy treats bleeding as a reason for assessment, not as a diagnosis in itself.
A scan gives the answer, and sometimes only a second scan a week later does. That wait is the heaviest part of the whole process.
Say it plainly when you phone the practice. That you are bleeding and pregnant is reason enough for an assessment.
When should you make contact?
Call your GP or midwife about any bleeding during pregnancy, certainly when there is pain with it. Thuisarts, the patient information service of the Dutch College of General Practitioners (NHG), advises immediate contact for heavy bleeding, fever, or severe one-sided pain.
That last combination matters, because one-sided pain with bleeding also fits an ectopic pregnancy. That is a different situation and needs prompt assessment.
Keep track of how many pads you soak per hour. That is the measure practices steer on, and it is immediately usable on the phone.
And afterwards
Most early miscarriages come down to a chromosomal error that arose spontaneously, not to anything you did. That is worked through in what causes a miscarriage.
If you want a sense of the odds in your situation, miscarriage risk by week gives the figures by week and by age. The full overview sits in miscarriage: symptoms, causes and tests.
Write down the date the bleeding started and how many weeks along you were. I keep repeating that because it is precisely what gets asked in any follow-up conversation, and it is hard to reconstruct later.
Every blood test result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
