Pros and cons of a transvaginal U/S?

TW; mention of sexual abuse

I'm planning on going for my first scan at 8 weeks and 2 days. My referral is for an abdominal but they offer a transvaginal as well and I know that it'll show a lot more and I'll get to hear the heartbeat but with a history of sexual abuse I'm on the fence about having somebody down there and inserting something. I know once it comes time to deliver those fears will need to go out the window but for now I'm not sure how to keep my nerves and anxiety in check so I can do the transvaginal ultrasound. Any advice is appreciated, as well as pros and cons of doing the transvaginal. ☺️
