Told I'm having a girl but keep having dreams it's a boy?


So at my last appointment I had dr write down what I was having. I was 15+4. I get an ultrasound at each appointment (perk of living in germany) i didn't see the screen when he looked to see the potty shot and I think that's why I'm having doubts..I have another appointment coming up on the 23rd and will be 19+4 and am going to ask him to look again. Has anyone ever had a strong intuition on gender and been right? Btw this is my 4th pregnancy but will be my 3rd live birth. I had intuitions with my other 2 and we're right so idk why I'm being so weird with this one haha
