Feeling a bit worried..

I'm currently 28 weeks pregnant today.. last few weeks baby has been laying across my stomach in a banana position so I could feel every possible movement. Yesterday he must have decided he was getting too cramped because he turned himself around and is now feet down.. problem is I am struggling to feel kicks and movements I still feel some but not as strong but I think he is kicking towards my back now which makes it harder to feel.. I feel like a tightening where he is every now and then.. but not much else but occasional light kicked.. should I go see someone do you think? I'm still feeling something it's just a lot harder..

Ps baby keeps making me poop and pee.. not sure if that's because he's now on those areas..
