A normal cycle lasts on average 28 days, but anything between 21 and 35 days can be considered normal. Therefore, a menstrual cycle of 25 days is quite common. Pay particular attention to the signals from your body: do you experience a lot of pain, extreme mood swings, or does your cycle vary each month? If so, it might be wise to seek additional support, such as supplements for hormones during menstruation. For instance, Vitex agnus castus (chaste tree), which promotes a normal and regular menstruation*. Please note: this is purely informative and in no way replaces medical advice.
