Do women overshare ?

If you have read any TG fiction at all, there's a good chance you read something like this: a new girl discovers that girls can be very ... earthy and share intimate details with other girls
.
Well, I don't know how common that is in real life, but I had something like that happen to me yesterday. I had a conversation with a co-worker, in which she ... overshared details about her period.

I hope I didn't come across as clueless in my response ...
