Endometrial biopsy worried about results

Hi all

i Had an endometrial biopsy 11 days ago following an ultrasound scan that showed a very slightly thickened uterine lining. I am 29 y/o and have PCOS. I have been experiencing bleeding between period for the best part of a year now. My gynaecologist said he would sent the biopsy on a 2 week referral. Today I had a call asking me to come into the hospital for an appointment this Saturday (2 days time) he even said, his clinic starts at 9 but he will see me at 8:45am before clinic starts. I am PANICKING. Has anyone ever been called in so urgently for good news? Has anyone ever had an endometrial biopsy come back normal and still had to have a face to face appointment?
