For the ladies who've had their first ultrasound!

Kennedy • Married to my soulmate since 7.4.2020!💍💞 We have a 4 year old son, who took a year and a half to conceive! We are expecting baby girl March 11th 2021 after 2 1/2 years of ttc with fertility treatments 💖
When they did your ultrasound did they tell you what ovary you ovulated from to create your baby?! When she was doing the ultrasound she looked at my ovaries and said "Yep looks like you ovulated from your left ovary when you got pregnant!" I was in shock when she said that, I didn't realize they could tell at all! How about you ladies? Anyone have any idea how they two? Im very curious.
