Measuring behind at 6w6d scan

Sophie

Hi Ladies, I wondered if anyone had any positive stories? I went for a scan today and should have been 6w6d or 6w5d based on ovulation. Baby and gestational sac measured at 6w0d so 5 or 6 days behind. I have had 2 miscarriages and 1 chemical pregnancy in the past year so obviously a little concerned. Does anybody have any experience of this and then baby being fine. Baby did have a heartbeat but we weren't told what bpm it was at. I've also been ill with an awful cold for the past few days so don't know if that would have had an effect. Any experiences will be greatly appreciated!!!!!!
