Tender breasts, headaches, stomach cramps, muscular pains, lower back discomfort, exhaustion, bloating, joint pain, acne, and diarrhea or constipation are all signs that your menstruation is approaching. A period, commonly known as menstruation, is the process by which your body sheds the uterine lining accumulation. It is usually experienced as a menstrual flow lasting 2-7 days where blood stains your underwear and other clothing items red. However, it can be different for each woman. Your body has many ways to get rid of the buildup of cells in your uterus without bleeding, such as breast swelling, pain, or changes in your mood. Menstrual irregularities such as heavy bleeding or absent periods can be symptoms of more serious medical conditions.
