time of the month

One player had bouts of nausea and by tracking their cycle over a long time they realised it was related to a certain time of the month.

He added, "Don't want them having a bad day or that time of the month, or whatever."

On average, the downtown Los Angeles weather station reports 2.47 inches of rain for this time of the month.

You're tied to co-workers, on a glacier, in icy conditions, and then you realise… it's that time of the month.

Scientists still don’t know how much certain associations matter, whether, in some cases, they make a certain time of the month ideal for avoiding or leaning into a particular kind of workout.
