Feeling like you’re going to go into preterm labour?

I’m only 35 weeks and as silly as it sounds yesterday I really didn’t feel ‘right’

People have told me my belly has dropped which is obviously normal BUT the tightenings, movements, hardness, just feel extremely weird and full on. I woke up an awful lot through the night with pains in my lower tummy (I put them down to needing to urinate) but whenever I move I just don’t feel right. I understand some people may be reading this like what on earth is she on about it’s just baby getting bigger but I just feel off, anyone else have this?
