well i'm 22 weeks pregnant, baby has been nudging me here and there over past couple of weeks although not that often. On Sunday there was a lot more nudging but not much over the last 2 days, although i went to a very loud concert last night and it was flickering a bit (the noise must have woken it up or it didn't like the music!). is this normal? how often should it be kicking and should it be regular?
