No yolk at 5weeks

Brittney

I went toner today for cramping I’m BaRLey 5 weeks pregnant. All of my quants have been great and more than doubling they did US and they saw the gestational sac in the uterus but didn’t see yolk sac yet but again I’m just now five weeks. I can’t help but stil worry…. Anyone had this and went back and yolk sac and all was there next time? My quant should have been 1600 it was 2464 so it’s rising excellent.
