I hate to tell you this hun but it gets soooo much worse. Lol.
I was complaining about my sore back around the same time as you, now, i wish i could go back to that!!
And complain away, your pregnant, such is your right!

And if anyone tells you to stop, just say, "do YOU have a human being growing inside you? Taking most of the vitamins and nutrients out of the copious amounts of food YOU eat? Having well placed kicks right into YOUR spine at 4am (and many times during the day)? Having to carry around an extra ten kilo's at least, which is all out the front and pretty much equates to the pain of having Pammy Andersons boobs plus Carmen Electras PLUS your own sitting right there and pulling your spine into what honestly feels like a silly straw???? No?? Then bug**r off!" Hahaha
