No sac

I’m 5 weeks and 5 days now, got positive blood test and home test , I went to the doctor yesterday because i had really bad cramps and she didn’t see anything no sac she said it’s early to see anything and she mentioned something about my uterus wall, she said it’s thick and it’s a positive sign and told me to come back in a week to check again she gave me pills because I had high risk pregnancies in the past but I’m so scared that it will be ectopic or something bad happen. Here is the ultrasound pic and tell me do you see something? And is it really a good sign that uterine wall is thick ?

Update: they found the baby at 7 weeks 💕💕💕
