It really depends on your situation, hun. I can only give you my experience and opinions.
With my previous, and first, pregnancy, I had s somewhat early scan at 9+1. We saw a strong heartbeat & the doc said to go ahead and get excited, start telling people. When I went in for my 13wk appt, they could not find the heartbeat. It turned out I had a MMC and the baby only measured 9+2. It was such a shock, and all the more devastating IMO after being reassured early on and thinking everything was OK.
I have gone back and forth a lot this pregnay over an early scan. It would be nice to find out what is going on in there ATM but knowing that ultimately- it won't change anything and what is meant to be will be...I have decided to wait until 12wks for my first scan this go round. I figure by then, some of the risk of MC has dropped and I will be able to have an abdominal scan rather than transvag (which I don't trust, for many reasons).
Ultimately it is your decision, hun. Just thought I would give my $.02.
