When do I see midwife

Olivia

So I’m not new to this I have 1 daughter and this is my 4th pregnancy but due to a genetic condition I have to have a date scan around 8/9 weeks and need to be booked in before.

So my question is it’s 6 weeks on Friday since the first day of my last period but I know that i ovulated what will be 3 weeks ago on Thursday (I have a 5 week cycle) when should I call the midwife to get booked in?
