First scan ?

When did you get a letter for your first scan?

I had my doctors app at 4/5 weeks pregnant and she said she’ll sort the midwife out for me and scan etc

I’m now 8 weeks and still no letter for anything at all? I had already got dates for my midwife and scan by this point when I was pregnant with my first

Should I chase them up or leave it? Am I being too impatient
