She stopped her periods...

Had invited this lady for Kunye - the Afrohouse event that happened this past Sato. Told her like a week ago. So she was psyched she told me she had even stopped her periods for this as she was sure she was getting laid after.

Now, this caught me by surprise, like, can ladies do this voluntarily? How even? All this time, why go through cramps if you can do that? Is this possible people?

UPDATE: From the comments, I've realised mkipanga mechi alafu akupee hio excuse, jua tu umenyimwa roho safi.
