Are you having your menstruation for the first time and want to know — how long does period last? Have you noticed your period for a while but its too short or long?

This guide from Medplux explains what a normal menstrual cycle length should be and several menstruation questions you wanted to ask.


What is period?

Period is the cyclical bleeding from the vaginal in women every menstrual cycle. It occurs due to changes in hormone in your body. The first time you notice your menstruation is called menarche. When you stop having periods its menopause.

Just after menache and before menopause, women experience irregular periods. During your period you may experience pain (Period pain). However, pain during period will not prevent your normal daily activities. In some women, period pain may be severe and may need medications to reduce cramps during periods (Dysmenorrhea).

Do you experience persistent heavy bleeding during periods? Then its abnormal. This is because blood loss during period can be heavy in the first few days of periods and get lighter as it ends.

Are you bleeding excessively with very large blood clots during period? Its abnormal too. Periods usually don’t have blood clots for long. If your period has big blood clots then its abnormal.

Though the volume of vaginal bleeding during period vary in women, bleeding more than 80mls is heavy menstrual bleeding.


Why do we have periods and what causes period in girls?

Period is due to shredding of the endometrium that covers your uterus. On the first day of period, follicle stimulating hormone (FSH) which is produced by the pituitary gland stimulates multiple ovarian follicles to grow.

As these follicles increase in size, they produces estrogen. Estrogen level will continue to rise before ovulation stimulating the pituitary to cause a surge in LH production. LH surge occurs 24 to 36 hours before your ovulation. If you understand your discharge before and during ovulation you can easily know your fertile days.

Ovulation will occur 12 hours after LH surge reaches its peak. After ovulation, progesterone is produced from the ruptured follicle that released the egg. Both estrogen and progesterone continue to build the endometrium.

When fertilization occurs, your baby (zygote) is implanted into the endometrium. However, if the egg is not fertilized, the endometrium comes out as your period.

Between 2 periods is your menstrual cycle length. It could be regular or irregular.
