Pregnant?

hey everyone! I'm Loïse! I'll just get straight to the point: I think I'm pregnant. With the emphasis on think.. so I haven't tested yet! I was supposed to get my period last Saturday.. I've been "nauseous" all week, especially when I wake up and before I go to sleep. My stomach is rumbling and it really feels like I'm about to get my period! This morning I also had severe lower back pain.. and I'm very hungry (which I always am Haha) but now it's really excessive.. who recognizes this & was/wasn't pregnant.. I think if I still don't get my period tomorrow, I'll grab a test. Looking forward to hearing your experiences!
