Anxiety! First ultrasound 😩

Kate

I’m getting a ultrasound in a few days and my mind is going mad. I have endometriosis and pelvic inflammatory. My doctor is working with me to get a hysterectomy. I’ve had a regular ultrasound before for my medical issues. However I’ve NEVER had a internal one and I’m in a state. I was raped as a little girl and the thought of a huge wand up in there sounds awful. How painful is it? And does it take long?
