Hi, I also had the same blood tests done. I cant believe your midwifes havenet spoken to you yet, they sound useless. I only found out my scan date at my midwife appt, I never had a letter through and Ill be just 13 wekks when I have the scan.
If I were you Id call and check if you have a date for your scan, cos you dont want to miss that!
Hope they sort it out x
