Ok seriously. i asked this already. nobody helped. my red eared sliders?

they mated today. the water is clear, i saw the tail along the other tail and his member inside. ok they mated, they bred. the female might be pregnant because the male is still breeding with her as we speak. so now what? what do i expect? i am putting them both in a shallow kiddie pool that is half land half water. so now what is it that i can do.
