A trans vaginal ultrasound is totally normal for your first tri.....if he didnt know how far along you were and they did a regular ultrasound the baby may be to small to see that is why they do the transvaginal i think that is what you are asking your question wasnt to clear...... but the fact that they didnt ask you anything was kinda weird but they didnt do that at my first appt. they asked all the questions at the second appointment
