Should be measuring atleast 8wks. Doc comes in a few hours later says levels are fine everything looks fine for early pregnancy can’t find no reason for vaginal bleeding says I’m good to go and follow up with doc in 72hrs! Now I’m super confused he showed no signs of worry n mentioned nothing of a missed miscarriage! Both techs can’t be wrong in their measurements right meaning baby would have stopped growing 2wks ago, dates not adding up why isn’t he showing any concern! Docs notes are also belie
