Baby favouring one side

So i'm 15 weeks and 6 days and my baby seems to be favoring my right side? i'll be on my back and there's be a hard lump while the rest is normal pregnant belly haha, and then ill touch the hard spot and he moves away back inside my uterus more 😂 like "mum, stop touching me!" haha. He was more to the middle this time and he was on my left side when i woke up the other morning 😂 it's so cute that I can actually feel him sometimes, I don't really feel kicks though yet, so i'm assuming it's his back or his head 😂
