I know im hopeless with things but i need help yet again!!Im booked in for my NT scan on wedesday and didnt have one with DD so have no idea but when i booked it the lady said i have to have a blood test 3 to 4 days before the scan and it had to be accurate ok fine but im booked on a wednesday so what day is 3 to 4 days before??do i count wednesday as a full day?so does it make it sunday?because no qml are open then or the monday or would that be cutting it too short?I know i might have to ring them i just didnt want to ring and sound daft on the phone!!
