Pregnant?

I've felt very close to throwing up lately(but haven't actually throw up). I've been have abdominal pain on my left side, kind of like cramps just not as bad. All I want to do is sleep. Gassy & constipated sometime too. If I am I'd be around the 2 weeks mark. Also my nipple has leaked a small amount of clear liquid this has never happened to me before until a couple days ago.
