37+4 babys position

Is it possible/normal for baby change positions so much and to lay sideways several times throughout the day?! whatever she’s doing, its SO uncomfortable. I can’t think of any other explanation to feel like she’s laying across my tummy. I don’t think it could be BH cause it’s only the top of my tummy that gets super hard and feels like so much pressure. Wtf is going on I’m done 😂
