Maddie, although being bumped about can feel unpleasant be reassured that your aeroplane can take it without any problem. It might not be as common over here but in some parts of the world it is and passengers are quite used to it. Of course, the smaller the aircraft the more pronounced it might be. Try and avoid sitting in or near the back as there you will be treated to extra discomfort from elevator and rudder corrections. Again, it's quite normal but can be unpleasant for some. Strangely enough I quite enjoy a tricky bumpy approach as it makes a change from the usual boring flying. I recall a particular one (also at BHX) in an A319 some years back. We were thrown all over the place on the approach and made a firm but good landing. I enjoyed every minute!
