Quick Take (TL;DR)If you’ve ever wondered whether your period lasts too long, ends too soon, or if changes without warning could be a problem, you’re not alone. At OhmBody, we’re rewriting the period rulebook—starting with growing an understanding of what’s normal. Because what’s normal for you may not be healthy, and “just deal with it” is never a good idea. Let's talk about what’s typical, what might need a second look, and how to talk to your doctor about anything that’s interfering with your cycle. |
How Long Should a Period Last?
A healthy period typically lasts between 3 and 7 days. Most women bleed for about 5 days, though anywhere in this range is considered medically normal for menstruating individuals of reproductive age.
| Period Length | What It Might Mean |
|---|---|
| 1–2 days | May be normal, especially for teens, those with low estrogen, or people on hormonal birth control. |
| 3–7 days | Considered a healthy, typical range for most menstruating people. |
| 8+ days | May signal heavy or prolonged bleeding (menorrhagia). Time to check in with a provider. |
What Affects Period Length?
There are many reasons your cycle might change over time—or vary from someone else’s.
| Factor | How It Can Affect Period Length |
|---|---|
| Age | Teens and women in perimenopause may have irregular cycles. |
| Hormonal birth control | May shorten or lighten your period—or stop it altogether. |
| Stress | Can delay or shorten menstruation. |
| Underlying health conditions | PCOS, fibroids, endometriosis, thyroid issues, or clotting disorders can all play a role. |
| Weight or BMI shifts | Rapid changes in weight can affect hormones and ovulation. |
What Counts as Heavy or Irregular?
It’s not just about the number of days. If any part of your period interferes with your daily life, it's worth exploring further. Signs of heavy menstrual bleeding (HMB) include:
- Soaking through a pad or tampon every 1–2 hours
- Bleeding that requires double protection (tampon + pad)
- Bleeding more than 5 tablespoons each period (that's 80 mL for our metric fans)
- Passing clots larger than a quarter
- Feeling exhausted, faint, or unable to function during your cycle
- Periods lasting longer than 7 days

When to Talk to Your Doctor
Don’t settle for “it’s normal for you” if your period length or flow is getting in your way. You deserve clarity, options, and science-backed solutions. Here’s when to speak with your provider:
- Your period lasts more than 8 days
- Bleeding is much heavier or lighter than usual
- You experience inconsistent cycles (less than 21 days apart or more than 35 days)
- You feel fatigued, anemic, or emotionally impacted by your cycle
How to Start the Conversation with Your Doctor
Bringing up any period irregularities might feel awkward—but it shouldn’t be. Your provider is there to help, and your cycle offers valuable clues about your overall health.
Before you’re appointment, try tracking your symptoms for a few cycles and bringing those notes to your appointment. You may want to gather:
- How many days are you bleeding?
- How heavy is the flow?
- Are you skipping periods or bleeding between them?
- Is your period exceptionally uncomfortable or even painful?
A simple opener like, “I’m not sure what’s normal for my period anymore—can I walk you through what I’ve been noticing?” can go a long way. You deserve to feel heard, and your personal experience deserves medical attention.
| Frequently Asked Questions | |
|---|---|
| Q: Is a 2-day period normal? | A: It can be, especially for teens, people on hormonal birth control, or during perimenopause. But if your period is consistently short and you're concerned, check in with your doctor. |
| Q: What if my period suddenly changes? | A: Hormones, stress, and health conditions can all cause changes. Track your cycle and talk to your provider if shifts persist. |
| Q: Can stress shorten my period? | A: Yes. High stress can delay ovulation or shorten the menstrual phase, impacting overall period length. |
| Q: What’s the best way to track my period? | A: Use a period tracking app, other health tracking wearables, or a simple notes log. Track flow, length, clots, pain, and any unusual changes. |
