Is the US Supreme Court preparing to overturn Roe v Wade?

Looks like that - judging by how they decided the case of the formerly pregnant illegal alien teenager who sought, and received, with the help of ACLU, an abortion.

The reasoning in the extremely short decision was as follows:

1.  The petitioner was pregnant and sought certain relief from the courts based on her pregnancy.
2.  The petitioner terminated her pregnancy and thus mooted (terminated jurisdiction) for her own case.
3.  The petition cannot at the same time end her own case by having an abortion (mooting the case) and continue to claim relief.

Guess what, in Roe v. Wade the petitioner also obtained an abortion before the U.S. Supreme Court reviewed and ruled on the woman's case - human pregnancy is much shorter than the judicial process winding up through courts of different levels, the window for an abortion is even shorter.

In Roe v Wade, a 1973 case, 45 years ago, the same U.S. Supreme Court claimed, in providing a full review of the similarly "mooted" issues, that the situation in the case is prone for repetition, but, due to the time limits of pregnancy and abortion, will always evade review.

In 2018 suddenly the same issues, "prone for repetition, but evading review", are mooted.

Which begs the question - is the U.S. Supreme Court playing games while preparing to overturn Roe v Wade as incorrectly decided without jurisdiction because it was mooted.

Or, is the issue of providing abortions to young women who came to the U.S. illegally so wide-spread and promises such consequences for the government and taxpayers that our "non-political" court was afraid to provide a full review and opinion on the issues involved?

Time will show - likely, soon.
