Not feeling so hot

I'm 11 + 4 and today got some strange dull,cramping feeling in my lower left hand side of my stomach along w some nausea. It's not intense,or bad necessarily but it's there and it's frustrating. The feeling comes and goes but I can't tell what it is. Can anyone relate or have a similar feeling ever? It's almost like I'm constipated but I don't really think I am. Ugh.
