Early Ultrasound

I went in today for an early ultrasound because I had a little pink of spotting when I wiped today. I'm 5 weeks 5 days and they could only see the gestational sac, not the yolk sac yet. NP said it was normal and examined me and didn't see any blood. She is having me come back next week to do an u/s again. I have such bad anxiety as it is and all I have been doing is looking online and I see positive and negative things that have happened in this same situation. Can anyone who has gone through this help ease my anxiety?
