I have had this in the past but for the last 4 nights I have woken up soaked!!! I even took my nightie off at 2 AM and this morning it was still wet!
Now I am only 37 and have had no periods in 3 months (this is being investigated by a usually slow NHS)....
I don't think it's pre-menopause as I have had this in the past but I don't recall having it so badly....
