I'm 5 weeks today by LMP (8th Feb CD1).. I had intercourse on the 23rd Feb, my first bfp was 5th March and I have not tracked ovulation. I had an early scan today to see if the pregnancy is in the right place and all that was seen on the screen was a small gestational sac measuring 3.3mm by 2.3mm with no yolk sac inside... she said she expected to see more at this point. I had my first hcg beta draw today and its at 2232.8 - has anyone else been through anything like this and what was the outcome? UPDATE: Second hcg beta came back today at 4976 so it's just over doubled! I have a scan booked in 5days... Keeping everything crossed!
