I feel nauseated and I feel small cramps is this a sign of something?

Nausea all through pregnancy is normal.  The small cramping is ok too.  Most women get small cramps through out pregnancy.  It is just your uterus growing and your body getting ready for the big moment.  Now if they come in intervals then begin to come sooner and then they get stronger as they come sooner then I would say you were in labor.  As always you should ask your ob doctor to be certain and if you are ever really worried go to the hospital.  No one will get mad at you for being concerned they would rather that you came in for nothing than to wait and have something happen.
