Can anyone help?

Amanda
I'm so nervous, my period hasn't hit me yet and three days ago I was spotting for four days and it's stops. I'm not spotting anymore but my period still hasn't came. I have been cramping I've been eating a lot but I'm not craving things I would usually do like before I come on. I also haven't been cranky much. My breast don't hurt but they are tender and soft. Idk if I am pregnant cause my sister told me to wait two more weeks(basically when the month is over) to go to the doctor. But I never been pregnant don't know what's going on!!! I'm nervous and scared.
