cramping, cramping, cramping

Kirstin
Hi Ladies,
11 DPIUI and I've been cramping for the past 5 days. I'm anxious as this has never happened this early before. Hoping it's a good sign. With occasional backaches here and there.
Glow says to test, but I'm too nervous. I'm scheduled for a blood test this Friday. My cervix is high and soft. 
Anyone out there experienced new cramping one week before BFP? Trying to pull some hope here. 
Thanks xoxo
