I'm scared

So my last last ultrasound was when I found out what I was having and that was when I was 23weeks.... Anyways they told me I was having a little girl and ever since then I bought everything for my little girl lol. But whenever I go out with friends or family they always tell me I have a boy belly and now I can't stop thinking about it since I'm almost due. What if my ultrasound changed or something. Ugh I hope I do have a little girl lol. First child smh
