Do you consider period and menstruation to be synonym words? Do you agree there has to be bleeding for it to be considered a period?

I saw this post on Reddit

https://www.reddit.com/r/asktransgender/comments/143q5oj/how_do_transgender_women_have_periods/

People are saying things like period and menstruation aren’t the same thing. Trans women can have periods because they have hormone therapy and take estrogen pills and can have periods symptoms like bloating and mood swings but they won’t have menstruation which is the bleeding part.

I disagree. I have always thought menstruation and period mean the same thing
