Help!!

I just found out I’m pregnant. This is my first child and I have so many questions! What should I expect for the first few months? When will I be able to find out the gender? When should I go get an ultrasound? When can I hear the heartbeat? How will I be feeling? What symptoms will I be having? When will I begin to feel the baby move? Is there a certain way I should sleep? Is there certain foods and drinks I should have more of or stay away from? I need to know everything there is to know! Please help!!
