My girlfriend wants me to remember her menstrual period. Why?

Because when women arrive at M, some will become strange-tempered, while others will be weak. Anyway, it's that time. You should follow her and take care of her more carefully than usual. Moreover, it is necessary for a boyfriend to remember his girlfriend's M-date, birthday and measurements. It is not that you need to remember them when you go to bed, but that it is the boyfriend's responsibility to remember these things. Also, when she comes to menstruation, calling mom or cooking blood-enriching soup such as donkey-hide gelatin stewed chicken is second to none, at least it can prove her mind. It's like I don't have the conditions to make soup here, but every time my girlfriend comes to M, I will buy a pack of that packaged candied dates to enrich her blood, at least it's delicious.
