Your period came, you bled for a day, and then it stopped. Maybe it came back the next morning. Maybe it hasn’t come back at all. Both happen to a lot of people, and most of the time the answer is in how long the bleeding lasted overall and whether you could be pregnant.
Is it normal for a period to start, stop and start again?
Usually. A period isn’t one steady flow. The NHS says the bleeding tends to be heaviest in the first 2 days, and on lighter days the blood may be pink or brown. A period lasts 2 to 7 days, and about 5 is typical.
Inside those days the flow can drop to almost nothing and come back. Healthline gives two reasons. The lining of the womb doesn’t come away at an even pace, and a bit of tissue can hold the flow back for a while before it passes. If the whole thing still fits in about a week, a quiet day in the middle is part of a normal period.
Cleveland Clinic says some variation in the amount of bleeding from one cycle to the next is normal too. What it flags is flow that’s much heavier or much lighter than you’re used to.
Why did my period stop after 1 or 2 days?
Two days of bleeding is inside the NHS range, so for some people it’s a normal period. If yours usually last longer, look at what changed this month.
- Hormonal birth control. The pill, the hormonal coil, the implant and the injection often make periods shorter and lighter, and some stop them.
- Stress, weight loss or a lot of exercise. Healthline lists all three as reasons a period stops and starts.
- Pregnancy. A short, light bleed around the time your period is due can be implantation bleeding. There’s more on that below.
One short period after a hard month is usually a one-off. If they’ve stayed short, the guide to a light period goes through the causes, and the guide to how long a period lasts shows where yours sits.
Period started then stopped. Am I pregnant?
If you’ve had sex since your last period, it’s possible. The NHS says some people get a bleed that looks like a very light period, with spotting or only a little blood, around the time their period is due. That’s implantation bleeding. It’s lighter and shorter than a period, which is why it often reads as a period that started and stopped.
A pregnancy test answers it. If the bleed was lighter than any period you’ve had, take one.
Bleeding in early pregnancy can also be a miscarriage. The NHS says to call 999 if you’re bleeding and have severe tummy pain, shoulder pain, feel faint or dizzy, or are soaking a pad soon after putting it on. For light bleeding with mild pain, contact an early pregnancy unit or 111.
Why did my period stop and start again a week later?
If the bleeding stopped for several days and came back, it’s probably not the same period. A bleed a week or more after your period ended is bleeding between periods. On hormonal birth control it’s often breakthrough bleeding, most common in the first months of a new method. Polyps, fibroids and infections can also cause it.
The NHS says bleeding between periods should be checked by a doctor, even when it’s light. The guide to bleeding between periods covers the causes, and if the second bleed felt like a full period, see two periods in one month.
After having a baby and in perimenopause
Bleeding that stops and starts is common after a birth. The bleeding after birth, called lochia, can get redder and heavier for a while when you breastfeed, because feeding makes the womb contract. Periods that come back while you’re breastfeeding are often irregular at first. The guide to your period after giving birth has the timings.
In perimenopause, the years before periods end, the American College of Obstetricians and Gynecologists says periods can come closer together or further apart, and flow can get lighter or heavier. A period that starts, pauses and starts again fits that. The guide to tracking periods in perimenopause says which changes to tell a doctor about.
When to see a doctor
A quiet day in the middle of a normal-length period isn’t a reason to book an appointment. These are.
- The bleeding goes on for more than 7 days in total.
- You soak through a pad or tampon every hour for a few hours in a row.
- You bleed between periods or after sex.
- Your periods were regular and have become irregular.
- You have severe pain, sickness or vomiting with your period.
Healthline lists each of these. If bleeding with pain is heavy and you could be pregnant, don’t wait for an appointment. Use the NHS 999 advice above.
How Plum counts a period that stops and starts
We make Plum, a period tracker app for iPhone, so this part is about our own app. If you log a period day, skip one or two days with no bleeding, and then log bleeding again, Plum keeps it as one period. Your day 1 stays the first day you bled, so the pause doesn’t push your next prediction back. A gap of three days or more starts a new period.
You can log each period day as light, medium or heavy, and spotting separately. That keeps a light brown day from counting as a new start. The guide to what counts as day 1 of your period explains why that date matters. Plum shows no ads and never sells personal data.
