Could I be prego ?!?

So I cramped really bad for a week before my period was suppose to start ... I was four days late && when I did start it was just spoting . It lasted the full five days but all it was spoting/light and that's not normal for me . Iv been coughing for a week with a sore throat ( I heard cold symptoms could also be pregnant symptoms) well last night I got a awful awful head ache but finally woke up around 2 am and felt really neasus then I knew I had to puke so I rushed to the bathroom. Today my nipples have been kinda tingly ... Any help ???
