Need a colposcopy- very scared

Susannah
I just found out I need a colposcopy (going next week). My pap came back abnormal for the second year in a row  (HPV test was negative) 
​Almost all year I've had abnormal bleeding and constant cramping. Could be from birth control. My mind is racing and I can't talk about it w/anyone. My gyn is amazing but I won't see her for a week and I'm going crazy! Has anyone else been through this? Im terrified the cause is pre cancerous cells or cancer
