Gender disappointment

I’ve wanted a girl since I found out I was pregnant. Everything pointed to me having a girl to , old wives tales, gender predictions and the ring test (I know these are all fake but it put hope in my heart) and everyone commented that they thought I was having a girl. When we went for my ultrasound and she was looking for the gender she told us to look away while she found it and no one but me did. My mom blurted “differently a boy!” Even though she knew I never wanted to know until my gender reveal. I feel so sad and disappointed and even angery I’m having a boy. I love my son but I really wanted a girl instead. I’m also mad the suprise was ruined for me....the best experience was turned into a shitty one and I feel so rude for saying I wish I had a girl. I don’t even really wanna be pregnant anymore honestly.... am I wrong for this? What is wrong with me and why can’t I be happy with what was given to me?
