Gained after training --- is it really water weight?

So after seeing plenty of posts about it here, I decided to try weight training on Saturday. I hit the gym for the first time in years and got a routine and did my first day of lifting.
Now, less than 48 hours later, I weight almost five pounds more.
I haven't gone over in calories (unless I underestimated something, and even in that case it can't have been more than 200 extra calories) and I thought I had eaten pretty well, but the weight is there again.

A lot of people here have said that after the first weight lifting sessions it is normal to experience a gain, but 5 pounds seems a bit too much, doesn't it?
Is there any way of knowing if it is water retention or if I need to re examine my diet? Or do I have to just wait for it to shed off on it's own again?
And if it IS water retention, any tips to make it go away faster?
Or do I just have to put up with it and wait until it goes away?

Thanks! :)

    Use logic here then. If you gained 5lbs of actual fat weight, that would be 17,500 calories excess. Did you consume that in 48 hours? No. So it's not fat weight. Guaranteed, it's not muscle weight. So that only leaves water. It's water.

    Yep, it is. Your diet didn't take a hit, so your muscles brought in water. Your scale may be showing added numbers, but you know that it's not because of fat. Relax and keep lifting. More muscles mean a better metabolic burn rate!

    If that is the case then yes, it is water.

    Simply give it a few weeks and it will disappear.

    Patience young grasshopper.
