I'm first and foremost a writer, so I always like to be grammatically correct in my sentences. Therefore, I always put periods in my...
could you only do it for some sort of 'very special coming of age' story or played up as some sort of gag?
...That's not the kind of period you're talking about, is it?

they're in female warrior stories all the time. one of my favorite books has them as how one of her male friends learns she's female it's a young adult book, so there's no stupid maturity rating connected.
Write what you know.
Do you have periods? Are you married or cohabiting with a female (have closely watched the monthly cycle with a sexual partner)?
I suggest doing something else otherwise.
Edited for the worst grammar mistake ever.
I would say that the Menstrual Cycle (and periods) are a very important (read prevalent) part of female life, and have a huge effect on daily (or weekly, or monthly) life style. The only reason I would avoid it is if your audience is of a younger age, it has no bearing on the plot (for instance the only time you do a scene of a person using the bathroom is when something is going to happen in or around the bathroom right), or if you don't know anything about it (in which case you could learn a lot from a google search or two cat_xd ). Otherwise, it's up to your writing skills. cat_smile
