27 weeks plus 5 days

This is my first pregnancy so I don’t know a lot and I rely on this app a lot for any questions or people who have the same symptoms cause it’s been really helpful. As in the top I am almost 28 weeks, never really had a rough pregnancy.. its been pretty good I can’t complain. But I have always been carrying low but it seems a bit lower and more heavier and lots and lots of more pressure on my lower abdomen and bladder. When I stand up it just feels so uncomfortable and heavy for a bit till I walk a little bit. Baby is only 2 pounds(last I knew) but I’m just wondering if this is normal? I don’t want to have him to early I want him to be in there as long as he can be but is this a sign at all or is this just normal?
