How can I better understand my wife’s feeling when she is on her period?

I think is fair to ask, but I am not sure what you want us to answer. Periods are very variable to each person, and each month is different.

I guess you could educate yourself on what is a period and what happens to us physiologically. But the most important thing is that you ask your wife how does she feel, and just listen to what she has to say.

Important thing. When women complain to their partners and spouses, we are not asking for solutions to our problems. We just want to vent and to be listened and conforted. That’s it.
