Gestational sac no yolk sac

Sadie

Had my first ultrasound yesterday I’m supposed to be 6w4d but it only measured 5w3d and no yolk sac. I did ovulate a day or 2 later than normal, I don’t go back for another scan for 2 weeks, has anyone else measured this far behind so early and everything has progressed fine? We had a loss in august and I’m worried. Had a few early symptoms but nothing like I had when I had my daughter by this point - I was full on gagging every moment of the day lol. Hate the not knowing either way, and 2 weeks feels like an eternity!
