Hello, I’m wanting to go for an early scan when I’m 7 weeks I’m just wondering how I calculate it. My last first day of my period was 11 December but I ovulated on 21st December. Do I calculate from period or ovulation date?

Thanks!

From the first day of your last period. Congratulations!

If I was you, I'd try to wait an extra week so you're over 8 weeks when you get the scan.

6-8 weeks is a high risk time for pregnancy but the odds of MC drop significantly if you see a healthy heartbeat after 8 weeks.

Thank you for letting me know. Do you know when I should refer myself to the GP? X
