Movement

This is my 3rd pregnancy so I know what it feels like to feel the baby move. I swear I'm feeling movement. I haven't had my due date confirmed by ultrasound so maybe Im further along. Its been almost daily I feel movement. I also feel like a ball feeling sometimes kind of like the baby is pushing on me. Thats how I've always explained it with the others. Its so weird cuz according to my last period I should only be 8wks but idk maybe I'm further along? Anyone else have this happen before?
