That happened to me a lot when I was pregnant! Could be position of baby, but more likely just uterus/amniotic fluid shifting to one side while you sleep (I remember asking my midwife and this is what she said). My bump stopped looking lopsided early-mid 3rd trimester when there was less space for everything to shift around 😂
Yes the bit sticking out is usually baby's bum! Amuses me a lot. I can see it move when I change sides or go from walking around to lying down. This week mine clearly went from lying horizontal to vertically because bump has not increased in size with a measuring tape but it's all going in thr front so looks huge if you look at me from the side and if you look at me straight on there is still a waist line!
@Alex omg his little bum 🥹 thats so cute! I thought it was his legs or something couldn’t figure it out
It’s probably baby is just mostly on that side. Through out my pregnancy bubba has always been on my right side. So it’s probably baby’s back is to your right
