I am somewhere between 4/5 weeks but when I had a chemical pregnancy a few months ago I put the form in and they sent me an appointment within 5 days for when I would’ve been around 7/8 weeks
I'd give it at least a week and call them.
Update: just got it through for when I’ll be 8 weeks
How far along are you? I contacted the doctors when I was about 4/5 weeks, and I didn't receive anything until I was just over 7 weeks, and that was a call from the midwife who scheduled my booking appointment.
