transvaginal ultrasound safe for baby?

Shenece

So I just made my first appt and I’m so excited.. it will be for my 8 week check up and they advised they could do a ultrasound but it would have to be transvaginal. Now I’m nervous because I seen that it could have some blood on it and that makes me nervous for the baby..how safe is transvaginal ultrasound and can I push to get the abdominal ultrasound instead?
