We 33F and 38M have been TTC for just over 1 year. I've finally started the referral pathway on the NHS and had my first blood test this week (day 21 progesterone)

I have an appointment for a transvaginal ultrasound in a month, obviously by then I will know if I'm pregnant or not, but my delusional and hopeful mind is still hoping for a successful cycle this month.

My question is, should I carry on with the blood tests and more specifically the ultrasound if I do get a positive test before the appointment?
