thankyou for your replies ladies, I rang my midwife at the drs, and she said to go down at 1.30. So i headed on down and explained what i was thinking, and she said "you know what jen, you know so much about all of this, you could take over my job!" lol. She said what i was feeling was right, we NEED the dating scan before christmas, so here are the forms.
So i got my scan for the 17th. See my midwife again on the 24th. so in the end i got my own way, which was the right way. thanks for listening
