Am i pregnant or not? i want advice please(:?

I'm pretty sure I am but Id love to hear from women who were or is to give me closure you know?. Weight gain. Excessive discharge and odor. Hot flashes. Sweating a lot more and easier. Naseau. I don't want to eat anymore but when I do its foods I don't really eat ever. Food repulses me. Everything leaves a bad taste usually sour or metallic. I can't sleep on my stomach anymore it has to be my side or it hurts and I can't breath. Little things I've always done make me winnded and my heart beat fast like walking upstairs. My memory sucks I forget the littlest things. Extremely horny and depressed/apathetic. Itchy all over randomly. Bumps that itch or don't some can pop but their not zits. Purpleish bumps on inner thighs. That's all I can think of thas been happening to me.
