unusual questioning or am I overthinking?

I had a pelvic & transvaginal ultrasound done on Friday. The tech asked when my LMP was and if I was using any contraceptives. I answered and she continued w the exam. While doing the transvaginal portion she asked AGAIN if I was using any contraceptives and then once more before she finished, this time she asked if I was on birth control. I'm aware that as a tech she couldn't give me any info, but I walked out worried. Has anyone ever had this happen? My results aren't available until Friday 😩
