[It is lovely]

The doctor help or assist please. Already some cycles successively for a week before monthly begin botched work, t. e. Monthly two weeks last almost. What is it can be? Really an endometriosis... Or what that still? I was couple of months back on reception at the doctor, to me did or made US and have told or said that all in norm or rate.
What analyses is better to make to find the reason?
In advance thanks, me of 27 years, Belgium
