I recently posted about my scan at 6 + 2 which showed me measuring for 5 weeks. I was told to go back a week later to check viability, since I was 100% sure of my ovulation date.
So yesterday I was re-scanned. The good news is that where before there was just a yolk sac, there is now a 5mm fetal pole and heartbeat.
The not-so-good news is that I am still measuring a week behind my dates (of 7+3) and a whole 11 days behind LMP dates and they've dated me 6 + 2, which means I would have tested positive 3 days after conception, in other words it's impossible. (I have a 31-day cycle and knew I ov'd on CD19). The consultant at the hospital seemed quite concerned about this and said miscarriage was still a 'higher than average' possibility for me - although he did say it could go either way and I may just have a slow developer (fingers crossed).
I really wanted this scan to show that my dates had 'caught up'. I know it is early days and there is a +/- 5 days margin of error, but I can't help but worry that I will lose this pregnancy just like the last one.
Has anyone else out there had early scans where you measured behind your dates, and if so, what happened?
Many thanks in advance.
