Ohhhh right! sorry! I thought that you were travelling due to work related purposes. In that case I would find an A&E, if nothing is wrong take it VERY easy from now on in and I dont know about concerts when you are pregnant either I know my mum was pregnant with me and went to a gig she said I was kicking like mad lol but it may be stressful as this is still early stages, you shouldnt be lifting a suitcase atall either. I work in a hospital and Im not even aloud to lift case notes!
