They do get a slightly yellow sticky discharge around the vents during certain times in the cycle. If it's slight it's probably normal.
Their cycle is only every 4 days and some females show more discharge than others.
If it is profuse though, bad smelling or blood stained or if she looks or feels slighly bloated or is drinking a lot it can be an infection which means an urgent vet visit.
If you get used to normal by daily checks you will quickly spot anything amiss.
The move shouldn't have caused an infection.
