Positive test!

Just took a pregnancy test this morning (my period is due to come Monday) and I got a BFP! I can't believe it and I'm in shock. We just started trying this month! Also it's hard to wrap my head around because although I've been having symptoms (very emotional and cramps and fatigue and even a little nausea) I don't FEEL pregnant. It's hard to imagine there's someone inside me! Does anyone else feel that way?
