With DD my dr gave me a referral letter, i called the maternity ward, they booked me in and organised a booking in appointment. They should tell you where to go etc.

Most of the time your GP will have ordered bloods and scans if your unsure of LMP.

This time round my GP faxed off my form and the hospital contacted me and booked me in and gave me a date and time to come see them, asked if id had bloods and scans done already, and that was about all.

Thats what ur GP is there for....dont feel silly....ask questions!!
