33weeks cramps and nautious

So I'm 33weeks 3 days and felt fine when I went to bed last night.... I woke up repeatedly feeling nautious and queezy but never threw up...my tummy was uncomfortable.. to start with it was sore when I was laying on my right side and then just sore/crampy/sharp pains in general no matter which way I was laying.... needless to say in curled up in bed watching friends and it seems to be subsiding but I'm just wondering if it's normal or something I need to worry about??
