Boy/Girl Gender Prediction

So I've been reading online about ways to tell if you're having a boy or a girl and I want a little girl sooo bad. If it is a boy I will of course love him just as much but I truly want a girl. With my symptoms I get nauseous throughout the day, but I've only thrown up once, I don't not crave sweets at all, just salty/savory foods. Lately Ramen Noodles (I know they aren't the healthiest but they are sooooo good, omg I cannot get enough) and I love laying on my left side. According to online tests those are all indications of a boy. Plus my Mother keeps telling me it's a boy. Lol Have any of you had these symptoms and had a girl? Lol
