Well firstly if you want to know if your axolotl is pregnant or not,  In truth they cant really be pregnant bacause axolotls do not carry babies, they have eggs.

 

You can notice this if there belly is very well rounded. The axolotl will probably start laying her eggs everywhere or where ever she can brush on, even the ground.

 

From then you can choose if you want to separate your eggs or not. But remember she will be laying hundreds of eggs!! you'll notice them of course they will have several layers of jelly like things around them.
