the big tummy theory was actually opposite for me, I was huge with my boy, much smaller with my girl. Intelligender was also wrong for my sister.
I would def trust what the tech says if you're that far along and she said girl, you're probably having a girl but you can do what @luv_my_lil said although my sister in law took a intelligender and it said boy but she def had a girl.
The big tummy theory isnt 100%. I look like I could be having multiples yet only having one and hes a boy.
I took the intelligender test at 10week said boy and sure enough its a boy... Walgreens sells them and intelligender.com.
They say bigger tummy is girl so if ppl r questioning twins n u/s tech says girl I say girl :)
Nothing you can do at home is accurate, and I'd definitely trust the U/S tech, I look like I'm carrying a boy 100%, and my little girl is definitely a little girl, 2 ultrasound techs at 2 different times got a clear shot.
What did the ultrasound tech say? How did she put it that she thinks its a girl?
I would trust the u/s tech before strangers on the street. But hey you never know.
