Which of these vaginal exams is the most invasive?

A fertility doctor is recommending I start with these. The cost will be about $1,200 out of pocket and I am concerned it will be too invasive ( I'm a cry bb for this exams). This will be my first apt with a fertility specialist. Been trying for the past 3 years on and off. His sperm is fine, so now is my turn and I am really nervous. Any tips or advice will be appreciated.
