4 weeks pregnant

[Brix1996]

I am 4 week pregnant, had to go for a scan due to 2 previous miscarriages.

Isit normal to just see a gestational sac at 4 weeks. It measures 2mm?
I’m so scared when I go back there will be no baby or heartbeat again.

Yeah 4 weeks is extremely early. I'm surprised anyone scanned you that early to be honest. Im 6 weeks today and my ivf clinic are scanning me this afternoon. They have warned me they only expect to see a sac and I have another scan appt next week for measuring foetal pole. Try not to worry
