anybody had these symptoms?

This is the first time I'm actually noticing something symptoms wise. Other times were kinda like in my head symptoms. But I've been have extremely sore nipples, Monday I went to the bathroom and had light light pink spotting, I've been cramping more, my lower right stomach has been aching, I've been nauseous but not to nauseous but I did have to take pepto this morning, and I've noticed that I have pain in my knees which I've never had before. My mom is taking me to get a test tomorrow because I told her and she said that it sounds like pregnancy. And right now my hip bone is aching. Does this sound like pregnancy?
