RIVER OF NO RETURN

Hitch, what do you mean by "major" menstrual problems?
Did Marilyn have an abortion during filming?

FWIW, I had severe menstrual conditions as a teen: almost paralyzing cramps, excessive bleeding, etc.
In fact, I finally saw a gynocologist for help when I finally moved out of my parents' house.
I remember that my mother wasn't too pleased about that (she was a control freak who couldn't bear the thought that I was an adult capable of making my own decisions!).
But, I digress--as usual, LOL.

When this movie was made, Marilyn was no longer a teenager, and--supposedly--her monthly cycle should have been regular, and there were doctors on the set who could have given her non-addictive pain killers.

To tell the truth, I'm curious to know in general how actresses handled "the curse".
But, I guess that will have to be the subject of another thread.
