One Day Period: Is It Normal?
When your period is on, it might feel like it’s never-ending. As such, it may seem quite relieving when your period ends earlier. You may be tempted to celebrate the early relief, but it’s abnormal for your period to suddenly go from its normal 1-week duration to only one day period. You may be dealing with something other than just having a short period to cut you some slack. Your period length might fluctuate for many reasons. If you suddenly experience a single day period, you have valid reasons to get concerned. But who knows? Among all the indications, it could also mean that you got pregnant. So don’t get worried. Lifestyle factors can also contribute to shortened periods.
A single day of bleeding during your period may sound convenient. On average, your period should last about 4-8 days. But if your cycle suddenly changes and lasts only a day, you have reasons for concerns. But as we mentioned earlier, don’t jump to conclusions. It may be due to pregnancy. If you are on certain medications, they could also shorten your menstruation. Some lifestyle factors also contribute to this. They include age, weight loss, and excessive exercise. Read on as we tell you what might cause a single day period.
What’s an Abnormal Period?
We think it’s better to use the word irregular period than an abnormal period. Because when we talk about menstrual cycles, we can’t affirmatively define anything as normal or abnormal. The truth is that some people have two periods in certain months.
So rather than seeing some specific numbers as normal, we should be thinking of ranges. There’s nothing absolute here. The normal length for a person might be abnormal for another. More so, this normal range can change at different points in your lifetime.
So then, if your menstrual period has a regular length, you can go to rest. The range is usually between 2-8 days. So long as you’re within that range, you’re safe.
But if the range changes, and becomes either too short or too long, your menstruation has become irregular. A single day period is not just irregular, it’s abnormal. But it may not be a cause for concern. Let’s find out why you may experience this.
Reasons For One Day Period
You may experience a light or short period when pregnancy occurs. That could last for only a day or two. And to be honest, if your one day bleeding is a result of pregnancy, then it’s not a period. The bleeding is due to implantation. Implantation bleeding is common.
Many women experience implantation bleeding after about one week or two after fertilization. But then, it can occur quite early on. It would not be a result of implantation, though. It would be because your cervix blood vessels are already developing and are, therefore, more likely to bleed.
Ectopic pregnancies, or what some people call tubal pregnancies, occur when your fertilized egg does not implant in the uterus, but elsewhere. The egg may be implanted in your fallopian tube, or cervix, or one of your ovaries. With the continual growth of the egg, it may rupture your fallopian tube and cause heavy bleeding.
Sometimes, you can also bleed from having a miscarriage. You can also mistake this for a shortened period. You are more likely to mistake this if you don’t know that about your pregnancy yet.
Miscarriage bleeding could be light spotting. And it could be a heavy flow too. It depends on how far your pregnancy is. Aside from the bleeding, you may also have abdominal pain or cramps. You should call your doctor immediately if you’re suspecting a miscarriage.
A light and short period may also happen due to breastfeeding. It is not unusual to miss your period while you’re breastfeeding. That happens because the prolactin hormone not only promotes lactation but also prevents menstrual periods.
You may not miss your period in some cases, but you might have light spotting. That refers to a period that lasts only a single day. Your period will return about 9-18 months after the birth of your baby.
Other Reasons for a Single Day Period
Hormonal pills and shots for birth control can shorten your period and make it lighter. That is because the hormones in them can make your uterus lining thin out. When your uterine lining is thin, the shedding will be less, and your period will be less intense. IUDs (Intrauterine devices) can also lead to the same effect.
Other meds, including OTC and prescription drugs, as well as supplements, can also lead to shorter periods. Such meds include:
- Blood thinners, such as aspirin
- Hormonal therapy meds (such as progesterone or estrogen)
- Nonsteroidal anti-inflammatory meds (NSAIDs)
- Cancer meds
- Thyroid medications
- Certain antidepressants
- Some herbal supplements, like turmeric, Gingko Biloba, ginger, and ginseng.
You should see your physician if you’re on any of these drugs and it’s affecting your usual menstruation.
2. Your lifestyle
If there’s anything new with you, your usual daily routine, it may affect your menstruation. Dietary changes and changes in your stress levels or workout regimen can also affect your period. Factors that can affect your period also include major weight-loss.
Skipped periods may also indicate that there isn’t enough nourishment to your body. Probably, you’re skipping meals.
3. Excessive exercise
Too much physical activity might also cause a single day period. This is common for endurance athletes who have been training hard for an upcoming competition. But then, those who recently changed their exercise level with no corresponding adjustment in your diet may also affect your menstruation.
Can it be a Health Condition?
The following health conditions can affect your period:
- PCS (Polycystic ovarian syndrome)
- Thyroid disease
- Other conditions that involve your uterus, ovaries, or cervix
- Cervical or uterine cancer
- Pituitary gland disorders
These conditions can cause one day period. So don’t assume you know what’s happening. Visit your doctor to be sure of what’s happening.
