Hicups are very normal so dont worry about the all my babies have had them, so expect that once baby is out it will get them after a feed as well which can mean they bring up some of there milk so go buy yourself some nice look shoulder rags for after feeds...

You will be feeling baby more now as like you said bub is running out of room... You will soon see lumbs and bumps sticking out all over the place, and if you try to push them back bub will only stick them out more....

Near the end of my PG I would see lots of knee's and arms, it looks very strange but its quite normal and amazing.... So take some photo's I wish I did or better still film it when Bub next has a good boggie in your tummy....
