You can usually tell if she is starting to push away things on the bottom of the cage with her back legs and remember she can't lay her eggs in the water so when ever you have time buy some sand and put it in a box or a shoe box and put your turtle in it while you are watching t.v. Or talking and don't leave your turtle alone because if you forget about her if you have other house animals she could be gone and she can get out because you want to put in at least more than three inches of sand. Hopefully everything works out and maybe you can watch her give eggs and take care of them. Write me back. Bye
You should probably ask a vet. But most females will begin to behave somewhat strangely in the period immediately before they are due to lay. Typical behaviour includes aggression displays towards other females, hyper-activity and climbing over obstacles, even attempts to 'mate' other water turtles(male or female) including making the high pitched vocalisations usually only heard from males. Females carrying eggs may also reduce their food intake, and sometimes may stop feeding altogether just prior to laying. Another way to tell is to ask your veterinary surgeon to X-ray a water turtle you suspect may be pregnant - although this is really only justified in ''problem'' cases. Hope this helped!
I don't know if my turtles is prego and I don't get what that girl said....
