Why Do Pimples Appear During Periods

Pimples appear mainly because of hormonal changes, not directly because of periods. During the luteal phase, hormones increase oil production in the skin. When pores get blocked with oil, dirt, sweat, or dead skin, bacteria grow and cause pimples. This is commonly known as period acne.

Why Do Periods Happen?

Every month, the body prepares for possible pregnancy. Hormones tell the uterus to build a thick, soft lining full of blood. Egg Is Not Fertilized If ovulation occurs but the egg does not meet sperm, pregnancy does not happen. Shedding of Uterine Lining The body removes the extra lining through the vagina. This bleeding is called a period and usually lasts 2–7 days. Women often use a period calculator for regular periods or a period calculator for irregular periods to predict this cycle.

• Periods (menstruation) happen because every month a woman’s body prepares for a possible pregnancy by building a soft blood-rich lining inside the uterus, and when pregnancy does not occur, this lining breaks down and comes out of the body as blood through the vagina. During this time, the uterus makes rhythmic tightening movements called uterine contractions, which help push the lining out, and these contractions can cause lower-belly pain, back pain, and cramps.
• The body also releases chemicals called prostaglandins, which increase cramps, make the abdomen feel heavy, and sometimes cause nausea or loose motion. Women may feel tired, weak, or emotional because hormone levels (estrogen and progesterone) drop right before and during the period. Many experience bloating, breast tenderness, mood swings, irritability, sensitivity, or sadness because the body reacts to hormonal changes. Some women also feel pressure or slight pain in the lower back and legs because the uterus shares nerve pathways with the back and thighs. Vaginal discharge changes into blood flow, which can be light, moderate, or heavy depending on hormones and body condition. These reactions are completely normal, and they show that the reproductive system is working properly.
