Measuring behind at 1st U/S

grace806

Please calm my fears. I am positive I ovulated either 10/8 or 10/9. The last time DH and I BD'd was 10/7 before he left for a week on a business trip. I was sick when he returned so we did not BD again. I had my first US yesterday and measured at 6w3d. By my calculations I should have been 7w1d. Baby did have a heartbeat so that's a plus. Also as soon as I got home from the dr my sore breasts were no more. So of course I start thinking the worst.

Anyone have experience with knowing their exact O date but measure a few days behind and all be okay?

Thank you!!
