Thank you for your question.
Generally a heart beat should be visible at 5 weeks on a transvaginal ultrasound. You can wait another two weeks after this to confirm that the fetus is growing. Having an extra ultrasound scan is OK especially if there is any concern about the viability of the pregnancy or if you have had any bleeding or spotting.
best wishes
