Thin womb lining

Hi , I'm 54 post menopausal for approx 8 years. All of a sudden I had a big bleed. Called Gp , got referred to gynae , I've had a scan, saw consultant on Friday, scan showed thin womb lining ,she didn't give numbers.. took 2 biopsies. So now have to wait . I am worried about what the results will show. I'm not on HRT , and she mentioned I may need a coil fitted, I had a bit of spotting after the biopsy , but today I'm full on bleeding again... anyone else in similar situation ?
