Welcome to the forum. I know you will find good advice here and I hope they will help you.
Do not despair as your duas will be answered. But they are not always answered in the way you expect them to be or at the time you expect them to be. Be patient and one day you will see that everything will work out. I know it is not what you want to hear, especially at 14, but such is life.
You repeated many times you feel unfortunate to be a girl. Do not be. As you mention, you are indeed blessed with the ability to create life. But there is so much more to being female than that. Keep in mind that if Allah decided to make you female, it means it is what was best for you. Do not worry, as time passes you will understand more and more.
