To ask for post war slang for having a period/menustrating?

[Thelowquietsea]

For a story that I'm writing. I'm not sure what slang would be most relevant in 1950s Britain to suggest a woman was menstruating.

Any ideas? Woman is lower middle class.

The curse or “is your friend here?”

My mom is 90. She always described it as ‘unwell’

I’ve always said on the rags 🙂

Yes, I'd forgotten "unwell" , my MIL always said that.

So many great responses. Thank you all very much.

I was born in the 50s and my mother didn't have a slang name for them, just always referred to them as periods.

However if she wrote a note to my swimming teacher she would say "Please excuse Noon from swimming lessons this week as she is indisposed"

I am in my early 40s and went to a secondary school built in the 1970s, but we had communal wall-mounted incinerators by the basins in the toilets all the time we were there. They couldn't cope with the amount of towels being put in them, or the towels would stick to the flap, so they were pretty grim really although we accepted them at the time. Now I am wondering when they went - I assume they have gone now! (Anyone go to Thornden more recently?)
