12w 2days bleeding and cramping

Jennifer
Started yesterday with pelvic pressure and pink/mucous discharge today its bloody, heavy and pain increasing/passing small clots - went hospital and they sent me home saying come back Monday when the early preg bleeding clinic is open and will scan me then. My first scan was scheduled to be on 23rd - I feel like the cramping means this isn't a good sign! :( anyone been in this position?
