I went to a gyn because I had not had my period for 3 years and assumed I was in menopause. But a month ago I had a one week period. I went and had an ultrasound and they said my lining of my uterus was .13mm. I was scheduled to have a sample tissue taken by the doctor said it was too hard and gave me prescription to soften it up. Then before I went back in the doctor called and said never mind just come in for a consultation, no tissue sample being taken. They also did some blood work. Any idea why they wouldn't do the sample??
