6 week scan no baby

Charlotte • 3 miscarriages 1 molar pregnancy TTC #2🤞🏼🌈

I went for a scan today at 6 weeks 1 day they saw the yolk sac and it measured 6 weeks but no baby was seen, is this normal has anyone had this and gone on to have healthy pregnancy & babies?

I have a re scan next week to see if they can find the baby.
