Gestational sac still no yolk visible.

Hi ladies,

So yesterday I went to my fourth check up within the last week and was told we still do not see the yolk but the gestational sac is measuring 7mm. The doctor called in a second pair of eyes and she said that she could see like a shadow possibly the yolk but could not say for sure since it was dusty 🤷🏼‍♀️. I know when I ovulated since I was testing so I know it’s super early but it’s just frustrating! My HCG levels were at 8500 from 3400, so it more than doubled in 48 hrs. I go back Tomorrow on Valentine’s Day for another repeat. All I can do is take it day by day and as long as there is no bleeding I’m ok 😊 just frustrated. Anyone else going through the same?
