Normal?.......

I have been having repeated mild but sharp twinges in my left side of my uterus/abdomen ... I slept on it, woke up and they are still there! I have no bleeding, no cramps, and heard a healthy HB yesterday, could it be growing pains even though it feels like it's in a particular area? I've had twinges like this but not in the same place for so long. 

My anxiety is consuming me!

Thanks for any replies ...
