I had an ultrasound today at 6 weeks exactly and the doctor prefaced by saying we would only see a sac but everything I’ve read online is saying I should have at least seen a yolk sac. To be fair, he only took maybe 30 seconds to do the whole thing but I can’t see anything other that the gestational sac which is measuring 13 mm. He said he saw “some bits in there” whatever that means but to come back in 10 days. He also sent me to get labs done that I’ve already done twice and they came back normal so I’m not sure the reasoning for doing it a 3rd time if everything is fine. I’m freaking out now. Anyone have some insight on this?
