3rd opinion

So i told my mom i was pregnant.. mind u I’m 31 with 4 boys 🙄. This go round it’s a girl 😍. She doesn’t seem to excited but whatever. So i asked her should i start buying little things right now(I’m 15 weeks). So she starts asking me if I’m sure it’s a girl, how do i know, if the ultrasound tech was good blah blah blah.. i had the tech to tell me at 12 weeks it’s a girl, i had a private scan @ 14 weeks and she said it’s a girl so should i go get another scan? For some reason she always gets in my head 😑. Oh yea here’s a pic
