Ultrasound at 7 weeks and 3 days

Me

I had my first ultrasound last Tuesday and I was wondering if anyone had any idea what is that object below the baby? The ultrasound tech didn’t seem to worried about it . But I never seen a object like the one in the ultrasound and this is my third pregnancy. I go back on October the 28 for another ultrasound, meet with the genetics nurse about doing testing ( I did the dating ultrasound and met with one of the midwives in the office last Tuesday.)
