I went in for a scan to verify pregnancy on Friday 10/21. I should have been a little over 5 weeks. But we didn't see anything. Not the sak or anything. She said she could see my endometrium thickening? But that's it. She told me to come back in two weeks. I ovulate around cycle day 20-22. And the only time DH and I had sex this month was the 1st because he's on a business trip. So I should only 4 weeks. Which is fine. I'm getting concerned seeing other people's ultrasounds from super early and seeing stuff. Now I'm scared. Anyone have any experience with this? I've had a miscarriage before so I'm super nervous.
