It's a monthly 'party' when grandma visits. Women have been menstruating since they were teenagers, so you would think you would know everything about it by now. But did you know that there are many myths going around about our monthly bleeding? Below we debunk five menstruation myths and have listed a number of facts that will put an end to these bloody misunderstandings once and for all.

1. Pregnant before the first menstrual period? It's possible

You can get pregnant a few weeks before your first period because ovulation occurs before your period. You are fertile three days a month. It is possible to become pregnant from the moment the first menstrual cycle has begun. You only get your period at the end of the menstrual cycle, so when you have sex you don't know whether this cycle has already started.

2. Your period does not (unfortunately) magically stop in water

Your period does not stop or slow down in the water. The back pressure of the water sometimes prevents the blood from flowing out of the vagina. Menstruation does not stop in the bath, shower or while swimming. If you want to swim during your period, it is wise to use a tampon or menstrual cup.

3. You can also get pregnant during your monthly bleeding

This is a common misconception that can lead to unwanted pregnancies. The chance of this happening is small, but it is there. In some cases you can get pregnant if you have unprotected sex during menstruation, because the length of the menstrual cycle differs per woman. If you have a short period, it also takes less time for ovulation to occur. You could then become pregnant up to five days after your period, because sperm can survive up to five days after intercourse.

4. You don't lose liters of blood when you have your period

Although it may feel that way to some women. In reality that is not the case. Every body and every period is different. As a result, one woman also experiences more blood loss than another. Blood loss is greatest during the first days of menstruation. You generally lose an average of about four tablespoons to half a cup of blood per menstruation. Girls who have just had their period lose even less. Of course, there are also women who suffer from excessive or heavy bleeding . Stress, nutrition, exercise and sleep are factors that affect your period. As a result, you may lose more blood one month than another when you have your period.

5. You can exercise when you are menstruating, but in moderation

Exercise is a way to relieve menstrual cramps and boost your mood. If you are able to exercise, you can do so as always. If you don't feel like making a lot of effort, listen to that and choose an activity that still gets you moving, such as walking, yoga or pilates. Wearing protection that does not get in the way too much during these activities is important, such as a cup or menstrual underwear .
