7+5 have another scan tomorrow and I’m terrified

Hans

Had a scan at 6+1 and got told baby was only measuring 5 weeks and no heartbeat yet. I have a scan tomorrow to check for heartbeat and measurements.

I’m terrified it’s not going to be there!

If it is, is it likely baby will still be measuring 1 week behind or could it measure correct this time according to period and ovulation positive tests which would be 7+5
