Follicular Check Ultrasound?

MissK
What happens in a follicular check ultrasound?? 
​I am supposed to go tomorrow, and I would like to know what to expect?
​This month was my first month on Clomid.  I do ovulate on my own, but my doctor felt like Clomid would boost my chances... I am 23 and have been TTC for almost 2 years.
​Any advice or help is appreciated!
​Thanks Ladies!
