Scared for ultrasound next week.

The hospital did an US on me at 4w+3 because of a possible ectopic, they couldn't see a thing.. nothing at all, which they did say could happen (PUL).

I have another US next week at 5w+4 and I am SO SCARED that there will still be nothing there, I feel sick to my stomach thinking about it, wish I could just sleep until Thursday :(
