10weeks and spotting..

Woke up this morning and when I wiped there was fresh red blood, I had a strange cramping in the bottom of my back which eased after I stood up from the toilet, I called the emergency midwife who has passed my details on to the early pregnancy unit and the earliest I can get in for a scan is 12pm tomorow.. I'm so anxious!! Still slight pink when I wipe and got period like cramps in my lower back! How can they leave it so long with out giving you answers :(
