Hi. I have had abnormal vaginal bleeding for a long time. I recently had an hysteroscopy and a polyp removed. . The biopsies have come back as benign. During the procedure the gynaecologist noticed my cervix was bleeding and I have been referred for an urgent colposcopy. My latest smear test was normal. 
I’m really worried and do not understand why I would have been referred for this with my last smear test being ok. Any support or advice would be really appreciated. Thank you
