Babychotu how did you go?
This is number 3 for me and I reckon it gets worse! You are more aware of all the things that can happen...
But you just have to not do anything silly (the obvious no nos) and take it easy.
After you see the heartbeat it takes the chance of something going wrong down to 2%
That is helping me this time after seeing a heartbeat at 5wks 6days

Good luck
