Okay so lately I've been feeling nauseous when I'm hungry and when I eat I don't really want to it makes me feel sick. When I kiss my SO I feel like I'm gonna puke from his breath that was just brushed. Last night I had a weird tingling sensation in my boobs and I've been super gasy... My boobs have also gotten bigger. My period was only 3 days and wasn't like it normally was. Could I be pregnant or is it just my head going crazy?
