Determine your menstrual flow isn’t always easy. If you need help, check out our article dedicated to this question: How can you determine your menstrual flow? Let’s talk more specifically about heavy menstrual flow. How can you recognize it?
Heavy flow—what does it mean?
The first thing to do is determine if your flow is truly heavy. It’s estimated that a loss of 50 to 80 ml of blood per cycle is considered heavy.
We know it’s not always easy to measure how much blood you lose during your period. However, you can rely on how often you change your tampon or pad. For example, if you change them every two hours and if you have your period during 7 days with the presence of blood clotsit’s highly likely you have a heavy flow.
Some signs are unmistakable:
- a maxi pad is completely saturated upon waking after a night’s sleep,
- you often stain your sheets or pajamas,
- pads that are too thin or regular just aren’t enough and get saturated very quickly,
- tampons leak.
In daily life, a heavy or very heavy flow can be bothersome, exhausting, or even disabling. Having to change your period protection several times a day becomes a chore. You have to plan, remember, and never forget to bring spares in your bag.
That’s why switching to period underwear is a real game changer. With period underwear designed for heavy flow, there’s no more need to worry or stress. You can go about your day and forget you even have your period.
