Ways to tell gender?

M • Loving life! ❤️✌️
So we had an appointment yesterday at 15+5 and I was really hoping to find out gender but baby wouldn't cooperate and had its legs closed 😩
Doctor thought she may have seen a little peter but wasn't positive and wouldn't confirm. We will have to wait another month until my 20 week level 2 ultrasound...I'm happy my doctor won't say anything unless she's positive about it and that baby is healthy but I just had my heart set on finding out and am so heartbroken now! Another month seems like so long to wait!
Does anyone have any good at home gender test suggestions or other things we can do to figure it out sooner?
