Help! 2 Sacs But No Yolks

I had my first ultrasound yesterday and the tech couldn’t find a yolk. She estimated I’m about 5 and a half weeks along so she said I’ll go back next week and hope to see the yolk.

Then my doctor met with me and said there were actually 2 sacs, but neither had yolks yet. She wasn’t surprised Bc I have a history of irregular periods so I might not be as far along as I thought.

The she got my blood work back today and my hcg is 47,000 but my progesterone is only 13. That’s lower than she said she’d like to see so I’m starting suppositories tonight.

Anyone else have a similar story and went on to have healthy twins?
