Question

What is menstrual periods.?​

Answer 1

During a normal menstrual cycle, the lining of a woman's uterus sheds. This cycle is part of a woman's reproductive system and prepares the body for a possible pregnancy. It is also called a period, menses or cycle.

Answer 2

Answer:

Firstly, it's not menstrual periods. It's either periods or menstruation.

Now, for your question, it is the monthly shedding of the lining of the uterus.

The uterus prepares itself to receive a fertilised egg every month by lining the womb with blood vessels so that the baby (if formed) gets its nutrition. But when the egg is not fertilised, the uterus releases the egg along with its lining.

This process usually lasts for 4-8 days and occurs every 25-45 days (differs from women to women).

And no, it ain't a taboo to talk about it :)
