I feel like throating up but never do, I am always tired but have no other symtoms. I don't really feel pregnant but we are trying. I am 5 days late on my period and I have normal periods it never late. A couple days ago I had cramps and lower back pain like I do when I get my period but I am not bleeding. I have been pregnant before but had more symtoms then I am now. Can I be pregnant or am I just stressing out about wanting to be pregnant?
