6w1d first ultrasound today

Gleefully

Got to see my little 🌈 bean today . Thought we were 6w5d but measured 6w1d. Hb 130. Does anyone know what that other white blob is? The doc said it may just be a polyp?

Update: this pregnancy sadly ended in a miscarriage at 8 weeks. After D&C and testing, we found out it was a little girl with trisomy 15.
