When to expect booking appointment?

Alison

Hi got our BFP last week, so excited we could burst! But phoned doctor to tell them and was told they do nothing and I had to self refer to midwife, which I did and am now waiting to hear from them. When is the booking appointment usually and do you get any advice before then? Feeling a bit in limbo. Things like the flu jab been told I can't have until seen midwife (as I'm not officially pregnant on the system yet) but it's prime time to get unwell and I work with children all who have bugs at moment.

Not sure what to do for the best?!

Thanks
