Well, have you ever had stomach cramps or diarrhea or some other kind of gas or gut pain, something going on abdominably that was not your period but kind of reminded you of your period?
I'm quite sure that there are many instances that can cause a cramping gut-wrenching feeling which you could say "feels like a period"
Cuz let's face it,. Is the shedding of the menstrual blood of the lining of the uterus. Transgender individuals who are born as biological males do not have a uterus. They can take hormones which if they had a uterus and they had a bloody lining, would maybe cause it to shed but they don't have that. But it's possible that taking the hormones might give them some kind of a gut cramp or bloating or discomfort.
I'm sure that if every one of us biological females out there was asked to list One symptom only of their period, within 5 minutes we'd have a list of probably a hundred unpleasant symptoms (thankfully not every single one of us gets these symptoms every single time but unluckily some of us get them a lot more than others)
I suppose if you're a biological male, and you're on female hormones, your nipples might get sensitive. All humans have nipples. They can get sensitive. And you can get bloated. You don't have to be a female for that. And you can feel crampy, not uterine crampy because they don't have a uterus, but crampy in general. And you can have diarrhea. And you can have a headache. And you can feel nauseated.
And maybe your blood pressure can fluctuate (mine does, I get faint sometimes on my period and it's not an iron related thing although biological males can have low iron too)
As someone who has experienced some of the worst symptoms of what we call "a period" for my entire life, I can agree that there are aspects to this event that do not include a uterus.
But that's as far as I'll go. Obviously unless someone gets an artificial uterus installed (I'm pretty sure uterine transplants into biological males is not a thing yet) then there's no way without cutting themselves that they can experience menstrual bleeding and they will not expense experience uterine cramping or, the pain of having cysts bursting on their ovaries or other such fun things that we go through.
