Gender issues. 🤔

In week 13 the dr told me that it’s a girl 95% and I am so happy that it’s a girl! I want a girl....but I don’t know why that I have this stranger strong feeling thats its a boy it’s not a girl....so am waiting to week 18 to see I am now 16 weeks 6 days. My next appointment at the 6th. Is it normal to have that feeling? Tell me what you think please and if you ever been in my situation 🙏🏼🤔
