Def try and look now and get the ball rolling.
With my first pregnancy I found out @ 7 weeks and my doctor told me to start looking and book ASAP
I didnt believe him, I wouldnt have expected anyone to book before 12 weeks, I wanted to just make it that far first!
Then about 10 weeks I started calling a few places so I could have the same hospital for my 12 week scan and the top 3 places I wanted were FULL! I couldnt get in at all!
I ended up having to go to a certain hospital due to my blood disorder so in the end it all worked out ok anyway
