I have this too! Had it with my second and now my third! Very strange feeling! I’d also love to know what this is! Haha it does feel like a kick even though you know it’s not!
Iv had this with this pregnancy too which is my 2nd. It was odd because it was like a little thud and you think what......that can't be lol. So yes I'm definitely with you on this one. Very odd. It has stopped now.
I had this earlier on in my pregnancy, I think it’s just everything stretching out and getting ready x
