38 weeks + 1 day! 😷

Over the last few days I've become SO tired, today I feel very off, almost feel like I could throw up :( 
Can't move my legs without pain in my pelvis/groin area!! 
Also baby is usually very active and kicks vet hard, since around 5pm yesterday he hasn't been kicking around as much although I can feel movement it's just not as strong! 
Helpppp! Has anyone else felt like this ? And does it mean anything in regards to labour ??Â
