A healthy menstrual cycle can vary among women, but there are some common signs to look for. Typically, a cycle lasts between 21 to 35 days and lasts around 3 to 7 days. Regular cycles without severe pain or excessive bleeding are generally a good sign. A healthy cycle may also include regular ovulation, which can be indicated by changes in cervical mucus and slight mid-cycle cramping. Mood variations and mild bloating are normal but should not be debilitating. If your cycle is irregular or you experience significant pain, it is advisable to consult your GP for further evaluation and guidance.
