Hi there! I'm Dr. Sarah, a board-certified OB/GYN with over 10 years of experience helping women navigate the ins and outs of their reproductive health. It's great to connect with you today.

You're curious about how long a period is *supposed* to last. That's a fantastic question and one I hear frequently. The truth is, there's no one-size-fits-all answer when it comes to menstrual cycles. However, understanding what's considered "typical" can help you identify when something might be off and warrant a chat with your doctor.

Let's break it down:

**What's Considered a "Normal" Period?**

Most women experience a period that lasts anywhere from 2 to 7 days. This means bleeding, from light spotting to a heavier flow, for that duration. Now, keep in mind, this is just an average range. Your cycle is as unique as you are! Factors like genetics, age, underlying health conditions, and even certain medications can influence your cycle length and flow.

Beyond the Days of Bleeding

It's important to remember that your menstrual cycle encompasses more than just the days you're bleeding. Your cycle starts on the first day of your period and ends the day before your next period begins. The average cycle length falls between 21 to 35 days, but again, there's a wide range of what's normal.

Possible Reasons for Variations

As I mentioned, several factors can cause your period to be shorter or longer than average. These include:

* Age: When you first start your period, your cycles might be irregular. As you get older and approach menopause, they might become shorter or further apart.
* Hormonal Contraceptives: Birth control pills, patches, rings, implants, and hormonal IUDs can all affect your period. Some women experience lighter periods or even skip periods altogether while using hormonal birth control.
* Medical Conditions: Conditions like polycystic ovary syndrome (PCOS), endometriosis, uterine fibroids, and thyroid disorders can impact your cycle length and flow.
* Lifestyle Factors: Stress, significant weight changes, intense exercise, and even travel can temporarily throw your cycle out of whack.

When to Consult Your Doctor

While variations are common, some red flags signal it's time to reach out to your healthcare provider:

* Periods lasting longer than 7 days
* **Bleeding so heavy that you're soaking through a pad or tampon every hour**
* **Skipping periods for 3 months in a row when not on hormonal birth control**
* **Experiencing severe pain or cramping that interferes with daily activities**
* **Sudden changes in your cycle, especially if you're sexually active**

Remember, you are the expert on your own body. If something doesn't feel right, don't hesitate to seek medical advice. We're here to listen, answer your questions, and provide the support you need to feel your best.
