I would say it is normal too. My DS was laying transverse (sideways) for alot of the pregnancy even up to 32wks. After I had him my tummy still bears the shape of him - lopsided to the right. Not sure if it will ever improve by itself, maybe this bub in my tummy now will correct it and favour the right side, lol.
It's not a big deal and every time I have a shower I think I will mention it to my dr, once I get to there I forget.
