Good question and I honestly can't think of a good reason for it. Except maybe to make sure that the other members of the tribe would know when a woman was not interested in being social or sexual.
Of course most women do their best to make it hard for men to know when they are in their period, especially in the professional world.
As for the hot flashes in menopause; well evolution is done with the woman when they run out of eggs so it doesn't care what happens and any changes are not continued in the genes.
The simplest answer could just be that the hormone rage causes problems with the emotions and there is no way to take that out.

well i dont think it is useful by itself, i would rather call it a clear example of the so called "trade-off" principle - you gain an evolutionary advantage, but you have to take it with some nuisance or even risk that is connected to it. The hormones play havoc in your body. That is a burden, little unpleasant sideeffect connected to the the evolutionary advantage of ovulating (=being sexually desirable =being able to atract males=make them be part of the family and help you) so often and not only once a year as most other mammals. the fact that women can ovulate many times in a year is considered very important in the evolution of long-term bonds between the prehistoric men and women.

In my opinion its more of a side effect due to hormonal changes. I dont think it has any meaningful evolutionary purpose. We do see that a lot in the evolutionary processes, some are causes and some are effects of the cause.

The hormonal changes give signals as to when the female is fertile and when she is not; which would in turn give signals to when would be the best time for mating. Usually women are in the worst mood right around the time of menstruation which would be the least fertile time and the best mood right around the time of ovulation.

Could it be that the change of mood during period is not caused by biology but by environment and cultural factors instead?
To falsify the above statement, ask: do other female mammals have mood changes during estrus?

I have actually heard this.....It may be a woman's body's subconscious response to not getting pregnant that month. The idea being that since it was to the evolutionary advatage for the guy to get the girl preggers, then it was a sort of "punishment" of sorts for him not doing so. I don't know if thats true or not, but it makes a good story.

It keeps away the hyenas and jackals which would normally prey on such creatures.
