What's going on?????

Ok, so tomorrow I am 34 weeks and last night I was having terrible pains along with contractions 3-4 minutes apart for about 2 hours.  I drank some water and took it easy after a long day.  Nothing seemed to help.  I was having a bit of pain in my lower back as well.  
In December and the first of January I was in the hospital due to contractions caused by a UTI.  I didn't have any symptoms just kind of sprung up on me.
I went to bed early last night thinking well, if it gets worse I will go into the hospital, but I fell asleep...great right!  I didn't sleep too much...tossing and turning and having some cramping and contractions here and there and having to pee a lot of course.  This morning I was still having the cramping and when I would get up and walk around or do anything with my DD I would have one or two.  I go to the doctor tomorrow, so I am pretty much just waiting it out.
What do you think it is???  Is my body preparing me for birth???  With my DD I was induced @38 weeks so I never experienced anything, so I am clueless!

Any time you have more than 4 contractions in an hour you need to go to L and D!

I'd get it checked out especially if it's not going away or getting better after drinking water and taking it easy.  Hopefully it's nothing but don't risk it.  Can you go to your dr's today?

I tried to go today, but ever since one nurse and one secretary quit things have been really tough for my doctors office.  I am still cramping and I have taken it pretty easy today and I have drank plenty of water, so if I am not feeling better after we go to dinner I am going in to the hospital.  
The only reason I didn't go last night was b/c I had been three times in less than 2 months.  The first time they didn't have a reason why I was contracting and just gave me those shots that hurt like **** to stop them three times. The second visit they found out I did have an infection (UTI) and they did the same exact thing.  The third time there was no reason, b/c I had just finished my medications for the UTI and they gave me those shots twice.  Just a bit overwhelming I guess.  I mean I still feel her moving, so I know she is ok, but your right I should've just gone in anyways.
Thanks for the advice;)
