booked an internal pelvic scan! 😊

Sam🎀👶🏻
Hi ladies, 
So after TTC for nearly 2 years I have booked myself in for a private self referred pelvic scan. I just need this reassurance to know I am functioning as I should. I am 25 and don't understand why I still haven't fallen pregnant after all this time 😩 I feel like a failure! 
I had an ultrasound last year and it showed no abnormalities, however I know this is a lot more in depth and looks at ovaries and tubes etc. 
Has anyone had this before and would be kind enough to share their experience? 
Thanks xx
