Transvaginal ultrasound hurt so bad

Tiyah

Im currently 6 weeks and 3 days. I had a transvaginal ultrasound today, we saw the heartbeat flicker, I got to see everything in all it's glory. Except I was cringing in pain the majority of it. Is it normal for them to hurt that bad? Should I be concerned? The last time I felt pain like that was when I had an iud inserted.
