My friend is on a women's discussion group and has been observing the education of women by some transwomen (and sending me screenshots...).
Apparently the effect of estrogen on transwomen's bodies (mood swings, bloating, cramps) is an actual period. It is the same thing as expelling menstrual fluid from your person. You can use "period" to describe any or all of these symptoms, and even doctors do so.
There are multiple types of sex including chromosomal, gametic and hormonal. And get this, when a woman goes through menopause her gametic sex changes. Wow!
Health information such as that on NHS pages re cervical cancer is actually clearer since it removed references to sex because "people with a cervix" is the correct descriptor over women. Information on men's cancers has been subject to the exact same treatment.
Anyone who disagrees with this is following their feelings and not the science. Oh yeah and they are also a t* and want trans people to die.
And there endeth your lesson....
