If you're wondering what happens if we take Unwanted 72 during periods, you're not alone. Many people are unsure about how emergency contraceptive pills work, especially during their menstrual cycle. This article breaks it down clearly, allowing you to understand what Unwanted 72 is, how it works, and what to expect if you take it during your menstrual cycle.


What is Unwanted 72?

Unwanted 72 is an emergency contraceptive pill. It's designed to prevent pregnancy after unprotected sex or contraceptive failure (like a condom tearing). The active ingredient in this pill is levonorgestrel, a synthetic hormone similar to the natural hormone progesterone.

Think of Unwanted 72 as a backup—not a regular birth control method. It's meant for occasional use when your usual protection fails.

How Does Unwanted 72 Work?

Unwanted 72 works mainly in three ways, depending on where you are in your menstrual cycle:

  1. Delays Ovulation: It stops your ovaries from releasing an egg.
  2. Prevents Fertilization: It makes it harder for sperm to reach the egg.
  3. Prevents Implantation: It alters the uterus lining to stop a fertilized egg from attaching.

The effectiveness is highest when taken within 24 hours after unprotected sex. It can still work up to 72 hours (3 days) later, but the sooner you take it, the better.

Can You Take Unwanted 72 During Your Period?

Yes, you can take Unwanted 72 during your period, but the real question is: Do you need to?

Let's understand the science and real-life impact.

Is Pregnancy Possible During Periods?

Many people believe that having sex during periods is "safe." While the chances of getting pregnant during menstruation are very low, it's not impossible—especially if:

  1. You have a short menstrual cycle (e.g., 21 days)
  2. You ovulate early
  3. Sperm survives inside your body for up to 5 days

So, if you have sex towards the end of your period and ovulate early, there's a slim chance of pregnancy.

What Happens If You Take Unwanted 72 During Your Period?

Here's what could happen:

1. No Major Harm

Unwanted 72 is generally safe, even if taken during your period. It's not toxic, and you won't be harmed physically by taking it at that time.

But if you were not at risk of getting pregnant (for example, you were on Day 1 or 2 of your cycle), then taking the pill might have been unnecessary.

2. Hormonal Disruption

Even though you're on your period, the high dose of hormones in Unwanted 72 can disrupt your natural cycle.

Some possible side effects:

  1. Longer or heavier bleeding
  2. Spotting after your period ends
  3. Delayed next period
  4. Mid-cycle bleeding

Why does this happen? Because the hormone levonorgestrel sends mixed signals to your body, confusing your menstrual cycle.

3. Side Effects

Even if taken during menstruation, you might still experience common side effects of Unwanted 72:

  1. Nausea or vomiting
  2. Headache
  3. Breast tenderness
  4. Fatigue
  5. Dizziness
  6. Lower abdominal pain

These are short-term and typically resolve within a day or two.

4. Reduced Effectiveness (If Taken Too Late)

If you're taking Unwanted 72 after the risk window (say more than 72 hours after sex), it won't be effective—even if you're on your period.

Timing is crucial. Period or no period, if you're outside the window, the pill won't do its job.

Real-Life Example

Let's say Priya had unprotected sex on the 4th day of her period. She panicked and took Unwanted 72 a few hours later. Here's what might happen:

  1. Her period may continue as usual.
  2. She may notice spotting again after a few days.
  3. Her next period might be late or early.
  4. She may feel nauseous or tired for a day or two.

But since she was already on her period—and assuming she doesn't ovulate very early—her actual risk of pregnancy was relatively low. She likely didn't need the pill.



When Is It Smart to Take Unwanted 72?

Taking Unwanted 72 is a good idea if:

  1. You had unprotected sex during your fertile window (usually days 10–17 of your cycle).
  2. You're not using any regular contraception.
  3. Your condom broke or slipped.
  4. You forgot your regular birth control pills.

If your period just ended or you have irregular cycles, it's harder to track ovulation—so using Unwanted 72 may still be reasonable in those cases.

If your period just ended or you have irregular cycles, it's harder to track ovulation—so using Unwanted 72 may still be reasonable in those cases.

When Is It NOT Necessary?

You likely don't need Unwanted 72 if:

  1. You had sex during the first 2–3 days of your period
  2. You used a condom correctly, and it didn't break
  3. You're on regular birth control and haven't missed any pills
  4. You're using an IUD

Remember: Taking the pill unnecessarily adds hormones to your body, which could affect your cycle and make tracking it harder.

Can It Stop Your Period?

Unwanted 72 does not stop a period that has already started. However, because of the hormone surge, it can:

  1. Make your flow lighter or heavier
  2. Prolong your bleeding slightly
  3. Cause spotting later in the month

But it won't "pause" or "cancel" your current period.

What If You Take It Multiple Times During Your Period?

Let's be clear: Unwanted 72 is not for regular use. Taking it multiple times in one cycle—or even more than once in a week—can:

  1. Severely disrupt your menstrual cycle
  2. Increase side effects
  3. Cause irregular bleeding
  4. Reduce its effectiveness over time

If you find yourself using emergency contraception often, it's time to consider a regular birth control method like pills, IUDs, or implants.

Can It Affect Future Fertility?

There's no evidence that Unwanted 72 affects your long-term fertility. It doesn't reduce your ability to have children later. But frequent use may mess up your periods, making it harder to predict ovulation.

For peace of mind and regular cycles, it's better to use consistent birth control.

When to See a Doctor

Even though Unwanted 72 is available over the counter, talk to a healthcare provider if:

  1. Your next period is delayed by more than 7 days
  2. You experience severe pain or heavy bleeding
  3. You keep needing emergency contraception often
  4. You're unsure about your pregnancy risk

Sometimes, a simple blood test or ultrasound can give clarity.

Final Takeaway

So, Unwanted 72 Side Effects: Key Risks to Understand In most cases, nothing dangerous. But it might have been unnecessary, especially if the risk of pregnancy was already low.

Here's what you can remember:

  1. You can take Unwanted 72 during your period, but it might mess with your cycle.
  2. It won't harm you, but side effects like spotting and delayed periods are common.
  3. Emergency contraception is a backup, not a regular method.
  4. When in doubt, speak to a doctor or use a period-tracking app to understand your cycle better.

Conclusion

Emergency pills like Unwanted 72 are safe and effective, but knowing when and how to use them is key. If you're taking it during your period, understand that while it won't hurt you, it might not have been needed at all.

Tracking your cycle, using regular birth control, and staying informed can help you feel more in control. After all, your body deserves knowledge—not panic.
