Growth progress / scan / measuring behind

I posted last week about my early scan being 5-7days out and I was very worried. I have had 2 early chemical miscarrriages in the past and this qualified me to see the EPAU team this week. They’ve scanned me today. There is around 7mm growth and I’m now measuring 3-4 days behind 7w1/2d instead of 7w4d (based on ovulation date).

They said this is a lot of growth and seems positive. No rescans now until 12 weeks.

I want to have hope, but seen lots of MMC stories with the same ‘catch up’ and then loss in a few weeks.

Just looking for realistic thoughts and stories of anyone who’s had a similar experience ?
