Transvaginal Ultrasound HELP!!

OK I am the type of person that just gets nervous going to the gynecologist for your check ups...although I have become very comfortable with my gyno which is awesome, but I have to get a transvag US at 20 weeks. Typical and normal I know...but what does it feel like? I looked up the instrument they use, doesn’t seem too intense. My biggest question, how long does it last?! 🤢

Normal gyno appts are easy, what like 20 seconds it seems 😂 I heard this US may take 5 min...ughhh...just makes me sweaty thinking about it. I’m about 10 weeks now. I got paperwork on all of what’s to come in the upcoming appts.
